Hey Matt, thanks for your reply. I guess busy mode's UI looks too much like I'm not being a "team player" to me, at least in the Chrome web UI. My ideal, and I recognize this may not align with your target market, would be snapping a single image to use as my avatar for the hour/day/week/month, with knocking before chatting, but no indication that I don't want to be disturbed. I do like the UI overall and think you've got a good thing going.
