1) Allow me to totally disable certain keys on the MX Keys keyboard eg: INSERT and CAPS_LOCK

2) Allow me to switch Mx Keys keyboard AND MX Master 3 mouse by pressing the easy switch buttons on the keyboard. Don't force me to press the mouse button too.

3) Show the battery level as a percent or estimated number of days remaining in the Options+ app.

4) MX Keys physical keyboard (next version): please add spaces between F4 and F5, F8 and F9 and also remove the extra key to the right of F12 so that the last F key is F12. Why? Because many developers use these keys all the time and rely on the spaces to 'find by feel' the right key. No spaces makes finding the right key by feel impossible.
