I have been noticing a lot of other MacBook users have an expose-like program running on their computers. It is some sort of fast application switching plug in. They press a keyboard shortcut and icons from all of their running programs show up on screen and they can select whichever one they want to bring to the front. Can someone please tell me what this is? It looks amazing! Someone told me it was Vitru Desktop but that just brought up Virtual Desktop results and I know it isnt a Virtual Desktop.
