Add a Full Screen toggle to Quick Settings Menu

I was getting really pissed off with Google Chrome (and other apps) and it's lack of a "View Fullscreen" option like you get on desktop versions (as opposed to Android).  I mean, FFS, surely the option to go fullscreen is much more important when your screen is 2" wide as opposed to 42"... Screen real-estate is at a bloody premium.

I saw some solutions, ranging from buggering about with installing hacky-kludgy apps to modifying each app through ADB.

In the end, I turned to good old TASKER again for a simple and elegant solution that requires no rooting or anything like that, just TASKER, AutoTools Secure Settings plugin and AutoNotification.

Just click on "Immersive Mode" and the menubar, status bar and soft keys (if you have them) will disappear leaving you fully full fully screeny.  Click on Immersive Mode again and 3,2,1 you're back in the room.  Neat.  Links and instructions to follow.
