Allow adjustable chat content width in Codex App

What variant of Codex are you using?
App
What feature would you like to see?
Please add support for adjustable chat content width in Codex App.
Right now, the chat body stays relatively narrow even when I hide the sidebar or make the window much wider. Most of the extra space becomes empty margin instead of increasing readable content width.
This makes long technical responses harder to read and requires much more scrolling than necessary. The issue is especially noticeable on high-resolution displays.
Possible solutions:
- A width setting such as Narrow / Standard / Wide / Follow Window
- A draggable width control
- An option to disable the chat content max-width limit
Platform: Windows OS
Additional information
This is mainly a readability and productivity issue, not a font-size issue. Zoom and font adjustments only help partially because they do not change the underlying layout constraint.

You spoke my mind, bro. I also encountered a similar issue while using the Codex app on Mac.
I second this request. The narrow chat window requires clumsy scrolling for code bases with longer lines. Expanding the chat window to fit the available width is an absolute requirement. Chat text should keep its current maximum width, but diff, patch, code blocks must expand to all available horizontal space.
Insane this isn't a feature
Here's a little more traffic to this much needed enhancement.
+1, would be a lifesaver
would really appreciate having this feature
Has anyone tried this? (https://www.reddit.com/r/codex/comments/1sp4r7w/make_codexapp_wider/)
Seems like quite a large patch to do this though, so I'm hesitant before checking the code and right now don't have to spare time to do that, its nice to have but not worth risking disrupting my main workflow if 3rd party patch that nobody else has commented on breaks it. Let me know if anyone else tries it / has thoughts.
Personally I'm going to wait for an official fix to the app, fingers crossed one comes.
