I think the one you replied to was referring the fact that Arc can have multiple windows (terminal) "attach" to same tab (tmux session), that has nothing to do with profile.

Zen can do that too. Check out: https://docs.zen-browser.app/user-manual/split-view

I use Zen extensively, no that's not the same thing.

In Zen, if you open two windows, they have different set of tab instances; in Arc, you have same set of tab instances.
