Describe the enhancement you want to request

Upon leaving, codex outputs something like:

Token usage: total=3,728 input=3,713 output=15
To continue this session, run codex resume 019ac229-77e1-7d22-bc19-c63042eefdb7

This is neat, and allows to jump back into the session very quickly. I'd add the Title of the session, so I can get back to a Terminal tab, and know what that session was about, and jump back at it if need be.
