I was a bit of a late starter to the iTunes craze so it took me a little longer than most to realise that in OSX, hitting the little green button in the top left corner made the player go into mini-mode. Yeah, I know, I'm a little slow...
But anyway, I was then reading in an OSX book that there are other apps that have similar features like mini-mode. It failed to mention what they are so I was wondering if anyone out there knows of these other apps and what pressing the little green button will do...
