So i put together some C++ code from myself and from samples around the web, and made a simple exe that just toggles the wifi on and off. I've cabbed it up, so that it will install into \Program Files and put a shortcut in \Windows\StartMenu\Programs called AKToggleWifi.
You can now add it to the Manilla launcher and it will show up as in the attached screenshot.
You can uninstall it from the Settings\System\Remove Programs.
I havent tested it on any device except my Tilt/Kaiser running a 6.1 ROM from Sakajati (Hyperdragon/Blackstone).
