Inference-free "Thank you" & Finish function for conversations

Off-the-cuff request, but I’m really curious if anyone else shares the sentiment! I always feel terrible after completing any specific chat session:

1. Do nothing — it feels unfinished, chat simply stays in the same sidebar menu as any ongoing projects.

2. Send a final prompt a-la “Thanks! We’re done here” — feels guilty, knowing a massive waste of inference/power/resources on those empty prompts. (Either way, it doesn’t fix the “procedural” status in the sidebar menu, just gives a psychological closure).

As the extension of the “Branch off” function, perhaps — is it possible to add a function akin to ‘🏁 Mark as complete,’ perhaps? There are similar feature requests, but not exactly for this user scenario, so I wanted to add it. (@Theo Browne or the team — please feel free to merge/close as duplicate, if this seems more suitable incorporated within other features for navigation/labeling/chat statuses in the sidebar)
