Navigate Between Action Runs Without Leaving the Thread View

When I open an action run, I can see the chat thread with the prompt and response — but to get to a different run, I have to close the thread and go back to the actions window to select it manually. There's no way to move between runs from within the thread view itself.

It would help to have previous/next navigation controls, or a persistent run panel, accessible from within the chat thread view so I can move between runs without having to navigate away and reselect each time.
