I wonder why they decided to go with traffic lights. It doesn’t really map at all to the things you want to express on a desktop OS. Yellow=hide car but leave it running, and red=… destroy car?

The funny thing is, it could almost work on something like iOS, where (if I understand correctly) focusing away from an app suspends it typically. So that could be the red button. I’m not sure what yellow should be. Maybe put the app into a sort of non-interactive mode where it stays on the screen but doesn’t do any processing, just queues up notifications.

Red = stop (close)

Yellow = yield (minimize)

Green = go (grow)

Makes sense to me.

		It makes sense to me as well, but mostly because I’m familiar with the UI in-and-of-itself. This is a website for computer programmers mostly, we’re exactly the wrong people to ask if a UI is intuitive. OTOH among the non-technical people I know they’ve haven’t often complained about this sort of thing, so maybe the real answer is just that this is something where not much explanation is needed in the first place!
