Hi, why not adding adjustable time-out for MX Keys Mini backlight feature? I like to extend the backlight off time to my liking and needs!!! If you also add always on backlight to the options that will be nice! I like to inform you that 1.38.397153 version sometimes changes my MX Master 3S mouse scroll wheel behaviour!!! I never did have a problem with previous firmwares. My scroll-wheel changes from free-spin to the other mode (I forgot the name, wheel just turns with click like behaviour). Please do something!!!
