Codex app on macOS: suggested changes size window is too small

Is there a way to make Codex app show suggested changes diff in a bigger window?
For now this seems like a maximum size which is awful, it only fits 5 lines and there is no clear way to expand it further:

I understand the frustration with the small suggested changes window on macOS. Currently, the app doesn’t offer a built-in way to resize it, which can make reviewing diffs cumbersome. A practical workaround is copying the diff into a separate editor for easier viewing, and hopefully future updates will allow a more flexible window size.

I was hoping I just missed a button or a setting, sad to know there is none for now. Thank you for your reply! I appreciate it!

Hey @stamaks, I see how inconvenient it is to work with long code when the Codex UI only shows a few lines. As mentioned by @ryanwiltonkims, there isn’t a setting right now to expand that view.

I’ll share this instance with our internal team. While we can’t provide timelines or status updates, this kind of input really helps improve things over time.

I agree with this issue. The current “Do you want to make these changes?” approval diff is useful for small edits, but it becomes very hard to review safely when the proposed change is larger or touches multiple files.

I made a small UI concept to explain the kind of improvement I would love to see.

My suggestion is not to replace the current compact approval prompt. The compact prompt is still good for quick, small changes. However, there should be an “Expand review” or “Open full diff” button that opens a larger review view before the changes are applied.

Ideally, this expanded view could reuse the same full diff/review experience that Codex already provides after changes are applied, but make it available earlier in the approval flow. That way, users can properly inspect the proposed changes before accepting them.

For example:

  • Keep the current compact prompt for quick approvals.

  • Add an Expand review button.

  • When expanded, show a full diff viewer with the changed file list and side-by-side diff.

  • Keep the same actions: Approve, Reject, and Ask Codex to revise.

  • For multi-file edits, show the changed files clearly in the sidebar.

  • For simple edits, keep the experience lightweight.

This would make strict approval mode much more useful, because users could actually review the proposed changes safely before allowing Codex to modify files.
