We Need a Statusbar that can be Pulled from Anywhere
The one thing that has bothered me the most about android ever since the days of the Original Droid was that there was no way to pull the statusbar or see notifications in apps that decided to use the full screen.
For instance, in some games like Temple Run there is no way to see the notification that you just got, check the time, etc. On my iPad I am able to just swipe from the top of the screen in any app and it will pull down the notification center, then just swipe up to get back to my current app.
This will be even more important if we ever get toggles in the notification bar, both need to come in the next version of android. These features are long overdue.
