The Codex App has inline comments on output/diffs and it has made such a difference for iterating. Like Delta I expect to see this adopted everywhere.

The interesting bit is this type of UI doesn't fit very well in any of the existing terminal TUIs, I have only seen it enabled working well in GUIs.

Thanks for pointing that out. I tried the Codex App before but didn't see that.

I want to like the app, but I'm not sure if it actually fits well to my use case. With my current setup I need to fully quit and restart it if I want to work on a different project (to get it to use a different API key) and I cannot work in two threads belonging to different projects at the same time.

Also I generally prefer to handle sandbox the entire agent and disable its internal safeguards. Beside any doubts regarding the quality of the relevant sandbox implementations, I have just gotten my projects to work better this way.
