I would find it extremely helpful if an option were added that if my MX Keys keyboard is being used when wired, the backlighting always stays on. This was a feature that I really miss from using my previous Logitech K800 keyboard.

Also, the ability to adjust the delay when the backlighting turns off in wireless mode would be welcome as well, but not important to me as an "always on" feature when the keyboard is plugged in.
