The shared named profile is handy, but how do you deal with one agent's actions spilling over to the others? For example, one agent logs out, switches accounts, or trips a site's rate limit, and every other agent on that profile inherits it. Is there a way to give an agent a forked or read-only copy of the profile's cookies?

This - for some scenarios I want the cookies shared (multiple agents watching eg fb marketplace), for others I want to have their own sandbox. And the GUI could indicate this eg. by putting tabs that share profile into blocks.

Not yet. For now, state-save in one workspace and state-load in a fresh one gives an in-memory copy, so a logout stays there. Fork flag can be done.
