It would be great to get the backlight on the MX keys to either be more predictive or responsive. I work in the dark from time to time and having to drag my hands across the keys to see them is annoying. If I had to plug it in to charge more often, that is fine. I keep the cable close. Maybe if the keyboard is in use the backlight can be set to turn off after a longer period set by a user. Like one minute increments from 1 - 10 minutes.
