I was hoping that the beta would include what users have been asking for for ever; adjustable timing for the backlighting on MX Keys. But it didn't :-(
MX Keys is the best keyboard ever...IF I could see the key markings! I run the wireless keyboard wired to at least get a somewhat longer backlighting, but it is ridiculous that we can't get a configurable timer for the backlight. I'd be happy to drain the batteries and be forced to charge it every day, or keep it wired at all times; JUST KEEP THE BACKLIGHT ON!
