Improved pull request "Files Changed" experience feedback

[Akash1134]

Important

You can opt in to the public preview from any pull request via ✨Try the new experience in the upper-right corner. You can return to the classic view by clicking the “switch back” link.

About the new experience

This refresh focuses on performance, accessibility, and clarity so reviews stay responsive—even on the largest pull requests.

What’s new ?

Performance 🚀

• Faster diff rendering with significantly lower memory usage.

UX ✨

• NEW: Comment and annotation indicators appear in the file tree to help you quickly identify files with comments, errors, or warnings.
• NEW: Pending comments are shown in the review submission panel so you can look over your comments before submitting.
• NEW: Local draft comments persist across page refreshes.
• NEW: Seamlessly switch between split and unified views.
• NEW: A new side panel helps you discover comments, including the ability to search for text while also providing quick access to errors and warnings (i.e. annotations) reported by status checks.
• NEW: The file tree is now resizable so you can take advantage of your larger display.

Accessibility

• NEW: Consistent keyboard navigation and screen reader landmarks added for better accessibility.
• NEW: Increased line spacing for readability—use Compact line height if you prefer a tighter view

What's missing? 🟨

As of the initial public preview release, there are some temporary limitations that will be addressed over time:

• Applying multiple suggestions at one time (i.e. batching)
• Reviewing a single commit
• Annotations on unchanged files
• Small screen (e.g. mobile device) responsive layout

While our previous experience had hard limits on large PRs, this new experience is being built to scale. That said, we’re increasing our limits incrementally. To start with, our additional current limitations are:

• Limited to 1,000 files
• Comments: 40
• Replies per comment: 20
• Alerts: 50

How you can help

1. Report bugs, edge cases, or usability pain points in the replies (screenshots/gifs welcome).
2. Tell us which future enhancements would make the biggest impact on your workflow.

Thanks for helping us build a better review experience—we read every comment!

[willmarcondeseso]

I would like to be able to scroll through the Pull Request while the comment modal is open.

Reason: When a comment is outdated, we need to look at the current version to check if it actually addresses the comment.

I really love this feature! THANK YOU!!!

[well-known-alex]

So annoying!

[dcumings]

Also the comments disappear from context when changes happen. It would be nice to be able to see them after changes happen. Bitbucket had a great implementation for this

[Bangkah]

yes

[William-Aspen]

Azure DevOps had a strong implementation of this. For reviewers, it’s critical to know whether their comments were applied as intended, and seeing them directly in the updated files makes that process straightforward.

[rtalexk]

Update: I just found out that it appears when there's enough space (1280px width). Here's the updated feedback.

I'd like to see the branch name in the sticky header at all times so that I can easily copy it when I'm reviewing a PR.

---

I wrote the following before thoroughly experimenting.

I'd like to see the branch name when the sticky header is shown (i.e., when you've scrolled to the bottom).

The reason is that when I'm reviewing a long PR and want to checkout the branch to continue reviewing it locally, I have to go back all the way up to see or copy the branch name and then go back to where I left off.

[nniesen]

Similar scrolling issue getting back "Conversation" or "Submit Review" when far down in a large PR. Maybe those could move over into the side navigation or maybe the sticky header briefly becomes a floaty thing when scrolling.

[RentecJeremy]

I came here just to comment "Thank you for the branch name in the sticky header". I can't tell you how many mammoth PR's I've had to scroll up, or duplicate the tab, or (insert method of getting branch name here)... now the branch name is just there and copy-able. 🤌

[albertoblaz]

Similarly, I miss having a sticky bar below the PR's title to have the "Conversation" tab/button visible without having to scroll bar to the top.

Alternatively, users could still do Cmd+Up to scroll up and then click on the tab, but doing so doesn't scroll if the focus is on the diff panel, so you need to click on the files sidebar or the page margins and then use the shortcut.

It's not a critical issue, but a little annoying.

[pakeeza2425]

I know exactly what you mean — the old sticky bar made it so much quicker to jump back to the Conversation tab. Right now the extra scrolling or focus-shifting adds friction, especially during long reviews. A persistent header or sticky navigation with the tabs always visible would be a nice quality-of-life improvement. Not critical, but definitely one of those small things that would make the workflow feel smoother.

[duduedufsa]

This update focuses on three essential pillars of a modern code review experience: performance, UX, and accessibility.

Optimized diff rendering with reduced memory consumption.

[rtalexk]

I find the comment indicators in the sidebar really useful. It might also be useful to have them in the "diff file header."

It's very useful when you've marked a file as "viewed" because you can see how many comments it has as you're scrolling without having to expand it.

[maaicondgl]

I agree.

[iifeiss780-wq]

https://github.com/orgs/community/discussions/5486

[dcumings]

[shrynshjn]

this is not showing up for me, rather i am getting a comment option on the pr level, having it on a file level would really be great, current i open two split windows to check my older comments and the latest code.

[eengelhardt]

this is happening for me too.

Some comments are showing up in file and some are not

[rtalexk]

Seamlessly switch between split and unified views.

This is really cool. Is it also possible to seamlessly toggle hiding white spaces? If that's achievable without doing a refresh would be amazing.

[jessehersch]

Thanks for the feedback.

• We are planning to support seamless switching of "hide whitespace-only changes", but no timeline yet.
• We are also exploring the implications of making this a user-level preference so it would be remembered/applied consistently across all PRs. Do others have thoughts/opinions on this?

please do this soon. it's been too long! This discussion is 4 years old, and it says the feature was asked for 3 years before that! So long that the original feature request is a dead link. https://github.com/orgs/community/discussions/5486

[Primajin]

It was actually working better in the old flow and there was even a blog post from Github: https://github.blog/changelog/2021-10-14-hiding-whitespace-is-now-remembered-for-each-pull-request/

[pakeeza2425]

The old flow worked better because features like "hide whitespace" were remembered per pull request, as GitHub highlighted in their 2021 blog post
. The new experience seems to have lost some of that convenience, so restoring those capabilities would improve usability.

[mustmodify]

remembering per-user and per-PR seems both obvious and would result in a significantly better experience.

[ericgreveson]

Thanks for the feedback.

• We are planning to support seamless switching of "hide whitespace-only changes", but no timeline yet.
• We are also exploring the implications of making this a user-level preference so it would be remembered/applied consistently across all PRs. Do others have thoughts/opinions on this?

Would it be possible to set "Compact line height" as a user preference as well? I like the changes overall but much prefer the original setting.

"Hide whitespace-only changes" as a user-pref sounds good.
Regarding line spacing, currently, compact mode is an option but the default is to be "extra line height". I feel like "Compact line height" should be the default (to match the current experience, but also because the greater code density from compact mode is in my opinion likely to be more useful to more people when reviewing, compared to the accessibility-focused greater spacing).

[rtalexk]

Clicking a line number always assumes you want to add a comment.

In the previous experience it only changes the URL to have deep linking.

[aaccioly]

Any workarounds to obtain permanent urls?

[arisacoba]

@rtalexk which browser are you using? Clicking the line number should just highlight the line, not open the add comment flow.

[rtalexk]

I'm using Arc Browser, but this isn't happening anymore. 👀

[thuringia]

This is so much better, I might go back from reviewing with the VSCode extension now 🚀

I love the new alerts panel, unfortunately it looks like pressing a to hide them doesn't work anymore.

Maybe we could have some grouping or clustering in the alerts panel in the future.
For example I would prefer to see alerts raised by the linter first, instead of "this line is not covered by tests".

[audreyality]

unfortunately it looks like pressing a to hide them doesn't work anymore.

When this feature comes back, it'd be nice if hiding the annotations also stopped them from being added to the clipboard when copying code.

[willsmythe]

Thanks for the feedback. We are planning to restore the ability to use a to hide annotations.

[mccrearyp]

@willsmythe any update on when this is getting added?

[jsync-swirlds]

In addition to using a to hide annotations, can we have a global (user) setting to hide annotations by default?
Having to tap a (which does not always work correctly, particularly for large diffs) for every PR in repos that overuse annotations (a distressingly common practice that makes review a painful chore) is irritating and we're still left with (often) dozens of files that now have no visible change because some irrelevant annotation happened to touch that unchanged file.

[mccrearyp]

Are you not planning on adding this feature back anymore? Did you forget about it? Do you need help? If you need the code here is what I was able to do to add this feature from my browser console:

document.addEventListener('keydown', (e) => {
  if (e.key === 'a' || e.key === 'A') {
    document.querySelectorAll('.InlineMarkers-module__markersWrapper--Fw1hl').forEach(el => {
      el.style.display = el.style.display === 'none' ? '' : 'none';
    });
  }
});

[reecefenwick]

I would love to see the file tree sorted alphabetically with folders on top, then files. It is quite jarring to have changed files in the middle of folders when viewing the file tree currently.

Example of current state

App.tsx
components/
hooks/
index.ts
styles/
utils.ts

Example of desired state

components/
hooks/
styles/
App.tsx
index.ts
utils.ts

This would mirror how the majority of developers view the code in their IDE

[reecefenwick]

Files below is preferable IMO for a more consistent experience

But I also would welcome files above, it would be a massive improvement 🙌

[franzliedke]

Indeed, files below would also be consistent with GitHub's own repo tree view.

[warp10]

I see the value in being consistent with the repo’s tree view; nevertheless, having files listed first can have some interesting use cases. For example, if a PR includes a changelog file or a “manifest,” listing files first would make it one of the first (often the very first) files shown, which I think is nice when reviewing code. In my opinion, that would greatly help the review process. Just my two cents.

[parasyte]

I recommend sorting the same way as git diff-tree, which is what I think the old view did.

Old view:

New view:

[richard-rance]

Most tools put the folders first but I wish the standard was files first.

The files in a folder typically describe its contents. For example READMEs, Changelogs, manifests, public functions/interfaces. The sub folders contain the implementation details. I would like to read those first when reviewing a PR (or writing code).

That lets me see if their description makes sense to someone who does not know the internal implementation details. Then I can drill into the sub folders that contain the described implementation to see if they match.

It also helps for languages, like golang, that have a vendor folder containing a copy of all dependencies. It would end up at the end of the PR which is perfect since I basically ignore it when doing a review. Right now I have to scroll past all the vendor files to get to the top level files. That can lead to them being missed.

[Nilomiranda]

I don't see the option to comment on the file itself, only on specific lines.

Some files just get stuck into a loading state, like this one:

The comments tab is really nice, I like being able to filter comments by author, makes it much easier to navigate the reviews and attend to the requested changes or overall feedback.

I have the same problems with "stuck info" for some of my files.

[Asfand6417]

Ok

App.tsx

[ia0-review]

Should there be a separate thread for the "loading state" issue? I'm afraid this might be buried because the "comment on file" issue has been fixed.

[adcoelho]

This is still happening for me when selecting "Files owned by me". They don't load, and I am unable to review. Any known workaround?

[jieyouxu]

Hi, I would like to play around with this, but I'm not seeing the opt-in mentioned in

You can opt in to the public preview from any pull request via “✨Try the new experience” in the upper-right corner. You can return to the classic view by clicking the “switch back” link.

Am I missing something?

[imanmahjoubi]

We are rolling this out to users slowly, you should be able to see it soon 🎉

[margaret-lin]

The tab for Ask Copilot seems to be missing, also when hovering over lines.

[vitorklock]

My team has the process of always asking Copilot "Any mistakes made? Review this PR" before doing manual reviews.
Just like @JayLathiaTR, I think that being able to talk to Copilot about all the changes is an important feature.
This would also be an improvement, because previously I had to manually click all checkboxes, sometimes more than a hundred of them.

[rr-jimmy-multani]

I'd prefer that this button stay since it's related to the PR and its changes.

[daira]

Feature request: allow people who object to AI (and there are many of us) to turn it off, completely, without the risk of accidentally using it by some misclick or dark pattern.

[3nprob]

Bug: This button is visible even if Copilot is fully disabled in user settings.

[Biglulux]

Asking Copilot to summarize the PR is important to my workflow, so I would like the Ask Copilot button to return to the Files Changed page as well. An alternative could be allowing non-main branch files to be attached to regular Copilot chat, since currently only files on the main branch for all repos can be attached.

[njvrzm]

Not sure if this is the sort of feedback you're after, but the :shipit: emoji does not preview in the review textbox in the new version 😅 . It does show up correctly in the preview.

[willsmythe]

Thanks for the feedback. We'll address.

[cmargonis]

On the topic of emojis, I really liked that I could type e.g. :idea and it would suggest the 💡 emoji. It would be great if this functionality were preserved (or even expanded upon 🙏 )

[KeithYeh]

1. I can't find "comment on this file" button in new UI

Old UI

2. How to hide alerts? I can toggle alerts by pressing "A" in old UI

[willsmythe]

Thanks for the feedback. Both are known issues we're tracking.

[airvision-tw]

Indeed! I am also missing this functionality in the new view.

[cristinadoroftei]

True, I use the "comment on this file" feature quite often and I switched to the old view just because it's missing on the new one 😿

[Smolyan91]

[xmfcx]

How to hide alerts? I can toggle alerts by pressing "A" in old UI

This is very important for me.

[julioag-rmd]

On the Files changed tab I can only see 19 files out of 66. Why?

[lucagiovagnoli]

Switched back to the old UI specifically because of the "Files changed" bug. It's pretty risky to review thinking it's all changes, but really it's only one commit.

[justingrant]

Confirmed that this bug still exists. Here's a more comprehensive repro, and showing the workaround which is to filter to a different commit, then to reset the filter to show all commits.

1. Click "View it on GitHub" link from email notification
2. Click on "Files Changed (11)" tab

Expected: see changes for all 11 files
Actual: only shows changes from one file, even though the commit filter claims to be showing all commits.

3. Click on Commits tab again
4. Click back to Files Changed (11) tab

Expected: see changes for all 11 files
Actual: No change from above: only shows changes from that commit

5. Click on Commits tab again
6. Filter to only one commit
7. Now reset commit filter to show all commits
8. Click back to Files Changed (11) tab
9. Finally, it works normally! All commits' changes are shown.

[justingrant]

@willsmythe Given the severity of the issue and the fact that that it's been present for at least 3 months already, I assume that fixing this (or finding a repro?) is hard. Do you need any more info to repro and fix this? I can repro it easily.

As mentioned by others above, this bug kinda makes the new UI dangerous to use so I'm gonna have to turn it off soon, which is a bummer. Please let us know when this issue is fixed so we can all turn the new UI back on. Thanks.

[anna-intellegens]

This has been driving me crazy. It happens every time I follow a link from an email, which for me means almost every time I go to review something I now have to remember that the UI is lying to me, which is infuriating!

[mdfox20]

Also switched back to the old UI because of this! I almost always open PRs from the email link, so this is a completely breaking bug for me.

[vengut]

I used to be able to click on a useful link to see the submodule diff in PRs but now its just plain text.
Old:

New:

Could we have that back pls?

[cdunford]

👍 any of the above; missing being able to see what changed; I have to flip back to do the old experience to do it

[Lachy-Antero]

Our release process heavily relies on the ability to click through to see the commit diff of submodules. Will be very sad to see this go.

[hsl0]

I want to see that nice summary of changes for non-GitHub hosted submodules, too.

[jlc6]

I would like to be able to see which commit I’m starting from and which one I’m going to in the changed submodules, as the old interface used to show.

[AminHeidaridahoee]

I also want to see the submodule commitId change in the file preview, it is necessary for our code review

[BE-Code]

It doesn't always seem to remember if hide whitespace was turned on.

[Scramle]

Currently, I think the toggle is just backwards. "Hide whitespace" turned on sets the query param to ?w=1, and turning it of sets it to ?w=0. Expected behaviour should be the other way around. So in @rmartins0's case, that link works as it should, as w=1 shows whitespaces and w=0 hides them.

[shahmir-oscilar]

I believe i was able to reproduce this. See steps at: https://github.com/orgs/community/discussions/163932#discussioncomment-13915305

[FeBe95]

Related: https://github.com/orgs/community/discussions/163932#discussioncomment-14012281

[warwick-kiwibank]

A certain order of the URL parameters triggers this bug. This works:
.../files?w=1&file-filters%5B%5D=.yml&file-filters%5B%5D=.tf

But if I put the hide-whitespace parameter after the file-filter parameters, it doesn't work:
.../files?file-filters%5B%5D=.yml&file-filters%5B%5D=.tf&w=1

The parameters are added to the URL in the order of selecting the options in the GUI. So, to avoid the bug, you need to show/hide whitespace, then apply file filters.

The old UI works as expected.

[Bangkah]

Same issue here on Win 11 + Edge 124. Worked after disabling “XYZ” flag. Thanks for the workaround!

[FLGMwt]

For file renames with long paths, there doesn't seem to be a way to reveal the original file name. The path is truncated to just the end of the new file name and the path link alt test only includes the new file name. The only indication that it was even renamed is the orange icon in the file tree:

New experience:

Old experience (where the file name change is clear):

[paulbrom]

Found another one... after a git mv, it's unclear in the PR where the file was moved to. Only the original location of the file is shown:

[ricekot]

Sorry if this was already pointed out above, but it appears that it's no longer possible to submit a review with replies only and no top-level comment. That is the preferred model in our team (over leaving replies one by one) to avoid spamming everyone subscribed to the PR with emails or notifications.

[kallioaleksi]

We have a PR with only 69 changed files, and we get the notification:

Due to the large number of changes in this pull request, only one file is being shown at a time.

This wouldn't be an issue if the sidebar kept track of which files are marked as viewed, but now I have to always go through the files one by one to see if I've missed anything while jumping from file to file.

[olmokramer]

I'm not even seeing that warning, on a PR with only 31 files, but still it's only showing 1 file at a time, making the review page unusable.

[paulbrom]

Yeah this is still my #1 complaint about the new experience. There should be a way to turn the single-file mode off.

[pdudits]

It's hard to tell whether this has been mention in 2000 previous comments or whether this is recent omission, but there's no way to show all comments in the view and hunting for suggestions to put in a batch has become quite difficult:

Shortcut I works (and it takes some attempts to see if it is I l or | on the help screen), but this action should be more discoverable.

[zipengwu]

Can I customize the destination URL for the new 'View Details' button within annotations? If so, where can I find the documentation for this feature?

[lanwin]

The new view works very well for me. But I noticed that when I disabled "Viewed files" within the file tree and then hit the "Reload" button (the one which appears when externel changes are detected). This one gets enabled again.

This does not happen when reloading the page via F5.

BTW whats still missing is a one click way to reset the viewed stat of all files. This would help especially before merge to do a full review again.

[rrotter]

• Split view diff uses up more horizontal space so I have to make the window far wider to aviod line wrap.
• On unified view excessive space between lines make seeing differences more difficult. I'm sure expanded inter-line spacing improves readability of prose for some people, but when you are specifically looking at diffs, this change makes no sense.
• Old version: files appear to be in alphabetical order; New version: order is apparantly random?

[brentswisher]

The new view works really well in almost all scenarios. I have noticed one where it is extremely slow, to the point that I need to switch back to the classic view to complete my PR reviews.

In TypeScript projects that use the Yarn zero-installs pattern, it is not uncommon to have hundreds of files in the yarn cache in a PR. This generally isn't a problem. GitHub shows them as binary files and I can filter out the .zip files to see what actually needs to be more closely reviewed. However, when I do this in the new experience, the files that remain after filtering (the ones I actually care about seeing) get stuck in a loading state and the content never appears, even if I let it sit for several minutes.

If I switch back to classic view, I am able to filter out and review the remaining files in the same PR pretty much instantly.

[weegeekps]

I work in open standards and open-source, and I'm hoping you can revisit your decision to limit to only displaying the first 40 comments and look to increase it soon. As an example, within the glTF repository it's not uncommon for PRs to have far more than 40 comments. These discussions are often long running and vital to ensuring we get things correct, so marking the discussions as "resolved" is not a solution for us.

Can you please provide us with a way of better handling this? As it is right now, only displaying the first 40 comments makes the new "Files Changed" experience useless for many of these large PRs. While the old method was slow and had its own limits, there are some clear examples where the old experience can show comments when the new experience is unable.

This is most egregious on this very large PR, where these errors in both experiences are problematic.

New Experience

Classic Experience

[louis-brann]

probably already mentioned here, but (this is a hard format to look at previous comments)

likes:

• better view of changes since last review

dislikes:

• editing a comment does not preserve markdown syntax
• refreshing page expands already-reviewed files

[alexandrachakeres-wk]

I don't like the following in the new "Comments" panel.

• "Jump to the comment in the diff" does nothing
• Clicking "No replies" at the bottom (I was thinking it'd bring me to the comment in the diff) just closed the whole panel
• The filters don't seem to do anything at all

I don't like in the diff how the comments don't show up inline -- only tiny avatar circles on the right side / not searchable if I try to find everywhere with someone's name.

Not sure if this has been fixed, but I got a ton of errors when trying to comment on multiple lines. Something like "End line number cannot be less than the start number". But all I did was use your UI to select the lines I wanted to comment on. I had to cancel my comment, reload the page, and switch to commenting on a single line instead of the range I actually wanted.

[valentijnscholten]

I don't like it that it's only showing one modified file at a time. Makes it very clumsy to review the PR, especially when you want to review multiple files at the same time because there are dependencies between these files.

[trueberryless]

This might have been reported before, sorry if I didn't find the thread...

Suggestions outside of review range show git diff on wrong line

When a suggestion is made in the same file where changes happened, but more than 2 lines before/after those edited lines (in other words: outside of the review range), this suggestion shows the wrong git diff as you can see in the example image below:

Line 17 in this example should not be empty as shown in the deleted suggestion line.

I hope this feedback helps, let me know if I should report bugs somewhere else (ping me pls)!

[danielrh]

Our code review process requires reviewers to leave - [ ] checkboxes and authors to be able to tick off those checkboxes to mark code done. Can you please help to fix this in the new UI.

• The checkboxes need to be checkable by anyone.
