It would be amazing if themes were supported. Ideally, customizable/uploadable themes would be perfect, but I would settle for predefined ones as well. Something that shows a pretty nature background image instead of the black/red solid colors.
My 4yo gets terrified by the look of the black nest on our wall and totally loses it when farsight turns the screen on. We've got to a point that I have to cover the thermostat with a poster for her to ignore it and be able to walk past it. (Before that I had to hold her hand to while walking past it.. no amount of begging and reasoning could convince her that it's not scary...)
I am hoping that a nice image would work with her and I could also see the temperature setting too.
