What version of the Codex App are you using (From “About Codex” dialog)?

26.224.1209

What subscription do you have?

Pro

What platform is your computer?

Darwin 25.3.0 arm64 arm

What issue are you seeing?

Since updating to 26.224.1209, the folder tree/hierarchy in the Review/Diff pane is gone

In the Review/Diff pane, the previous right-side folder hierarchy (tree view) that listed only the changed paths/files appears to be removed. This makes reviewing changes significantly less usable, especially in projects/monorepos with multiple top-level areas (server/client/ui, etc.).

Previously:

Right side showed a compact folder tree of ONLY changed folders/files
Next to it: the diff content
I could quickly understand where changes happened and navigate file-by-file within the relevant folders

Now:

The tree/hierarchy is gone
Review becomes a long scroll through diffs with much less context and navigation

This is a major regression for code review workflows and forces me back into the IDE.

What steps can reproduce the bug?

Open Codex macOS app
Open a git repo with changes across multiple folders (e.g., server/, client/, ui/)
Open the Review/Diff pane
Observe: no folder hierarchy/tree, only a flat/scroll-based diff review experience

What is the expected behavior?

Bring back the previous folder hierarchy/tree view (showing only changed folders/files) in the Review/Diff pane.
Ideally as:

Default behavior (like before), or
A toggle: Tree view vs Flat list

Why this matters

The tree view provided instant structural context and fast navigation for reviewing changes. Without it, code review is much slower and less reliable.

The folder hierarchy/tree view is still available. You now need to click on the "Review" button to display it. We received input from users that they didn't want to see it all the time by default, so it's now available as part of a focused "review" mode.

I would really appreciate being able to look at the file tree, code and conversation history. Currently I can now only "Review" or "Chat and view code with no tree"

The folder hierarchy/tree view is still available. You now need to click on the "Review" button to display it. We received input from users that they didn't want to see it all the time by default, so it's now available as part of a focused "review" mode.文件夹层次结构/树视图仍然可用。现在你需要点击“查看”按钮来显示它。我们收到用户的输入，他们不想在默认情况下一直看到它，所以它现在可以作为一个集中的“查看”模式的一部分。 <img alt="Image" width="153" height="37" src="https://private-user-images.githubusercontent.com/223546144/554949442-13cc5e56-5362-4659-9e2e-61ed9dc41915.png?jwt=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJnaXRodWIuY29tIiwiYXVkIjoicmF3LmdpdGh1YnVzZXJjb250ZW50LmNvbSIsImtleSI6ImtleTUiLCJleHAiOjE3NzkyNDUwOTgsIm5iZiI6MTc3OTI0NDc5OCwicGF0aCI6Ii8yMjM1NDYxNDQvNTU0OTQ5NDQyLTEzY2M1ZTU2LTUzNjItNDY1OS05ZTJlLTYxZWQ5ZGM0MTkxNS5wbmc_WC1BbXotQWxnb3JpdGhtPUFXUzQtSE1BQy1TSEEyNTYmWC1BbXotQ3JlZGVudGlhbD1BS0lBVkNPRFlMU0E1M1BRSzRaQSUyRjIwMjYwNTIwJTJGdXMtZWFzdC0xJTJGczMlMkZhd3M0X3JlcXVlc3QmWC1BbXotRGF0ZT0yMDI2MDUyMFQwMjM5NThaJlgtQW16LUV4cGlyZXM9MzAwJlgtQW16LVNpZ25hdHVyZT03N2E2NDEzNTA3NGMxZjczNDdhM2FhNzIwMTI4NDMxYjBkOTZlZTM3NmEwNTQ0MmEzMDE2YjU2ZWViOGU4N2ViJlgtQW16LVNpZ25lZEhlYWRlcnM9aG9zdCZyZXNwb25zZS1jb250ZW50LXR5cGU9aW1hZ2UlMkZwbmcifQ.kSu4MKFLqhvb3aeoEkv3NlCW9YPR4ZAo4gbJAcJVk40">

Could this feature be brought back?
If some users don’t want to constantly see the file tree, maybe there could be a setting or toggle to enable/disable it.
