Hey @dbsx, thanks for the suggestion!
Keeping multi-Bot work organized, and making it obvious what each Bot is doing and what’s waiting on you, is something the team is actively looking into. Keep an eye on upcoming releases.
The “start a fresh topic on the same Bot without losing the old one” part is also being tracked in this thread, if you’d like to add your vote there: Grok Bot: prune/compact an agent’s context without creating a new Bot
On the “default recipient” idea: Grok Bot already lets you choose and change your primary Bot. That’s the closest thing today to the routing switch you describe.
