Idea 1- allow user to set kybd backlight level/duration.

idea 2- an option to run with charge cable connected and keep backlight on.
Idea 3- an option to use the keyboard as a non-RF keyboard via USB. This might be good for 'all other devices' that do not support BT, it could be one of the 3 switched device connection options.

Go for it !!!!

Thanks, I really like the keyboard size and feel, its a great space saver I use with PC+Mac+Raspberry Pi.
