Out of all of the features this keyboard has (and there are many) it's infinitely frustrating that you can't set the fade-out time for key illumination or backlighting. My keyboard is plugged in to the USB constantly, there is is not issue with the battery doing dead. I'd like to leave key illumination and backlighting on continuously, or at least increase iit to 5 or 10 minutes. The built-in timeout is WAY too short.
