Killswitch-Manager is an applet that controls killswitches and enables you to turn off or on radio devices.
I designed this application to use the wireless toggle function key on my Lenovo laptop which has a single toggle function key for 3 devices (bluetooth, wifi and ultrawideband). I still need to figure out how to bind that applet to a function key (probably through HAL). If you want, you can contribute as described in the TODO file. Feedback is highly appreciated!
