Would be nice to be able to hide the notification area. My idea would be it would be visible say when you hold the button in the gesture area or it could be swipped up or maybe just hold finger in gesture area for a few seconds. It would also be nice if you could "minimize" apps to the notification area or just have a running app program in the notification area that lets you know what apps are currently minimized, this would allow you to keep your most used apps open all the time and not take up screen realestate.
