New iPad Multi-Touch Gestures

Multi-touch gestures definitely made the iPad more usable and enjoyable. I use them frequently, and I think they really work well on the large screen. The pinch to go home has really spoiled me, and I never really use the home button anymore unless I have to.

But what other gestures do you think Apple could implement to make the experience even more enjoyable?

I think a four/five finger pinch out from the home screen (the opposite of a four/five finger pinch in from an app) would be a great gesture to open the last opened app.

I also feel like there should be a gesture that could be used from anywhere to bring up spotlight search. That would be really helpful.

What other ideas do you guys have for new iPad multi-touch gestures?
