As shown in the figure, the area displaying ChatGPT changes in the VSCode extension is too small, making it difficult to see the details of the changes.

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.

Hmmmm, I'm also seeing some other design issues...

What can I say...

I agree with this view. I think the current design of GitHub Copilot Chat is at least learnable — in fact, most of it is learnable. If it weren't for its poor support for BYOK, I would hardly consider using Codex as my primary AI tool.
