Ability to freeze apps with a long press
For users with root access, provide a way to long press on an icon and choose to freeze the app. This will then add a badge or logo over the icon to show it is frozen. Then if you select that icon at any future point, it is instantly unfrozen and launched. For pro users, Apex could re-freeze the app if you exit the app and go back to the home screen (or optionally, once you have turned the screen off).
