Love the MX Master 3 and MX Keys so much!! Please add option to control how long keyboard backlight is illuminated for. I have the charge cable on my desk and willing to sacrifice battery lifetime for longer backlight time. ie. 5, 10, 15, 20, 25, 30 sec options.
Also, please add ability to remove devices from main screen. Unless I missed it! I now use one of my MX Masters at home, one at work. Want to remove home mouse from work computer.
