[Codex App] Add a setting to expand activity/tool call summaries by default

What variant of Codex are you using?

App, macOS desktop

What feature would you like to see?

Please add a preference that expands Codex activity summaries by default in the desktop app.

I'm referring to collapsed items like:

• Edited 1 file
• Explored 2 searches
• Ran 1 command

Right now I have to click these manually every time to see the underlying details. I often want to review exactly which files changed, what searches were performed, or what command ran, so the repeated manual expansion adds friction.

A setting such as “Expand tool calls and activity summaries by default” would be useful. Ideally it would apply to these collapsed activity groups as they appear during a turn.

Possible behavior:

• Off: keep the current collapsed-by-default behavior
• On: automatically expand activity summaries like edited files, searches, and commands
• Optional: remember the last expanded/collapsed preference globally

Additional information

This would make the desktop app easier to use for people who actively audit Codex's actions while it works, especially during longer coding sessions with many file edits, searches, and shell commands.
