Ability to switch between and manage running multi-agent sessions in Codex App

What variant of Codex are you using?

App

What feature would you like to see?

I would like Codex App to provide a clear way to switch between running multi-agent sessions and also manage them while they are active. When multiple agents are running, I want to be able to move between them, inspect what each one is doing, and control them directly from the app.

This includes being able to switch to a specific running agent, check its current progress, send instructions, stop it, or close it when it is no longer needed.
