When you run many background apps (e.g. GMD GestureControl, SwipePad: Hyperspace Launcher, HomeFlip, GYF Side Launcher) that add themselves to your ongoing notification panel, the list grows fast and soon it gets so long that it takes up precious screen estate, forcing you to scroll down whenever you want to check the real notifications from incoming messaging text, email, etc.
So, how can the apps be barred from adding themselves to the notification panel, thus also removing the icons that clutter up the top left corner of the screen?
Goto: System Settings > Applications Manager > Pick the app that you want to hide, then uncheck “Show notifications”
This feature is available on Android 4.1 Jelly Bean for now.
