Thanks for the reply. It's good to know you guys are keeping tabs on what the market wants, even if the market can't have it.
While I'm at it, I'll throw out a couple other suggestions:
1) Divide the bar in half to allow different actions with a vertical swipe, depending on which half of the bar you use. Left side could remain the app switcher, and right side could be this:
2) A single gesture for closing the currently open app, and then locking the phone, so the next time you unlock, it goes to the springboard, instead of re-launching the app you were using the last time you put the phone away.
Still a top notch app, anyway.
