As others have stated I wish the control panel was backlit and you could adjust the brightness of the clock display. I would also like to be able to change the power level when using the express cook feature. 
If you are installing this microwave and using the countertop to your left be aware of the how far out the door opens. Unless you are shorter than the bottom of the microwave, the door will impede your movement. This microwave is performing as expected for cooking and reheating.
