PLEASE put an option in Logi Options+ to turn off keyboard backlighting by default. It's a real pain in the neck. Every time I restart my PC, the backlighting comes back on, and then I CAN'T SEE WHAT IS ON THE KEYS. So I have to repeatedly hit the F4 key to turn the bloody backlight off so I can see what the keys are.
If the keys were BLACK, then the backlighting would be fine; but backlighting figures on a white background... what were you thinking?
P.S. I don't live in a cave. I have electric lighting in my study and office anyway, so I can read documents, etc. Isn't that amazing?
