Codex Desktop: Changes code-review panel is too short and difficult to scroll
What variant of Codex are you using?

macOS
What issue are you seeing?
In the Chat interface, clicking the “Changes” / modified-items section to review code changes opens a code review area with very limited vertical height. The code diff is cramped, and scrolling through it is awkward and difficult to control. The interaction feels unintuitive, especially when reviewing larger changes.
Steps to reproduce
- Open a Codex Desktop chat.
- Ask Codex to make changes to one or more code files.
- Click the “Changes” / modified-items entry in the chat.
- Try to read and scroll through the code review diff.
Expected behavior
The code review area should provide enough vertical space for comfortable reading and navigation. Ideally, users should be able to:
- resize the review area;
- expand it or open it in a larger/full-screen view;
- scroll smoothly and reliably within the diff;
- use a clear scrollbar or trackpad scrolling without the panel fighting the surrounding Chat layout.
Actual behavior
The review area is too short by default, leaving only a small code viewport. Scrolling is difficult to use and makes reviewing changes unnecessarily frustrating.
Why this matters
Reviewing generated code changes is a core Codex workflow. A cramped and difficult-to-scroll diff makes it harder to understand, verify, and trust the changes before accepting them.

This is related to #15108, but the request here is specifically about the vertical sizing and scrolling experience of the Changes/code-review area in the Chat/Desktop interface, rather than code being incorrectly laid out inside a VS Code sidebar diff window.
