It would be nice if the connection of an external keyboard could be detected as a trigger. I use my laptop on the go and at home with an external keyboard and mouse. The keyboard already has status indicators for Num Lock, Scroll Lock and Caps Lock. When connected I would like the TrayStatus indicators that are already on my keyboard to disappear and appear again when I disconnect the keyboard. That way I can always run TrayStatus in the background without bothering with starting/stopping it every time I connect/disconnect the keyboard.
It would even be perfect if it could be made dependent on the type of keyboard connected, if technically possible, because different keyboards can have different indicators. I use a couple of different keyboards.
