I have the mx mechanical keyboard, I'd like the backlighting to stay on full brightness no matter what I don't care If it burns the battery. It lowers the brightness setting automatically without prompting.
Also I'd like the option to remap keys such as the page navigation keys and the calculator keys to macros or windows task scheduler tasks for example, I'd also like the option to buy custom keycaps sets the default ones feel a bit cheap for the price.

also fyi the rubber on my mx master 2s mouse has degraded a lot and shrank which led to the thumb rest button being stuck activated which required some jerryrigging to fix
