Agent0 threads, your conversations with Agent0, now keep running when you open another thread or leave the page. Until now, switching away meant losing sight of the thread Agent0 was still working on, so you waited or kept going back to check.
The bottom bar, along the bottom of the screen, lists your running and recently finished threads. A spinner marks a thread that is still working, and a dot marks one that finished while you were somewhere else. Select a thread, or press ⌘+Shift+9 (Mac) or Ctrl+Shift+9 (Windows/Linux) and use the arrow keys, to return to its answer. While the page stays open, the prompt you had not sent and any follow-up you queued are still there. Removing a thread from the bar does not stop it. See Run Threads in Parallel.
