How about screen saver function?
I suppose that rotary encoder/footswitch and the LCD screen are the weakest parts in QC.
LCD might have burn-in effect or LCD failure in the long run.
So how about adding screen saver?
Obviously, it will be a disaster if LCD turns off in the middle of a show.
However, l’m afraid long turn-on time in bedroom and studio uses, as active pixels are almost identical with small changes over time.
