@BrowseGPT was also intended to be able to generate images for users in that channel, although we never finished the integration.
I appreciate the feedback here from users, but we can't vote to make site decisions on the fly. The chat system will be revamped though to fix leaving rooms not removing them from the sidebar.
Categories is another separate topic, Personally, I'd rather not introduce an AI specific category unless a lot of AI flooding the site became a problem. To me, that seems better suited for chat (like BrowseGPT works via DMs)
