This looks very cool. Does the window picker for multi-window apps work with the pinning? So if I have a safari windows I want to have associated with a profile, and the option-tab will ignore all the other windows?

It is a constant pain when I cmd-tab in a space with safari, and it throws me out of the space to another one because the window that gets focus isn’t the “closest” one on the current space.

right now it shows all safari windows not just the ones on your current space, so the "wrong space" problem could still happen. I'll look into Space aware window filtering.
