like a back button. but better.
This tweak will use a sliding panel-like configuration when one app launches another app. Then pressing the home button will act to send you back to the first app without returning to the homesreen.
No new icons are added to your homescreen. Configure the Activator method for the appslide back button from your Settings app. (it is the Home button by default)
