Research direction

The issue does not name files, tests, or entry points. Start by locating the desktop chat layout and existing preference controls, then determine how width modes should affect prose and tables. Done means the app offers Reading, Wide, and Full width behavior for chat content on wide desktop displays.

Description

app enhancement
What variant of Codex are you using?

App

What feature would you like to see?

The Codex desktop app constrains chat messages to a narrow centered column even when the app window is very wide. This makes responses unnecessarily hard to read and makes tables particularly impractical.

Please add a chat-width preference, for example:

Reading (current behavior)

Wide

Full width

Ideally, wide tables could use the available workspace width while regular prose can remain comfortably readable.

Environment:

Codex desktop app

Wide desktop display

Screenshot attached

This is distinct from terminal width/wrapping requests: it concerns the desktop app’s chat layout.
