Use an Arduino input for an ambient light sensor. if it is bright out change the display to light back ground/dark text to make it easier to read. then switch at night so it is not as in your face bright. This would be useful for people using this in a convertible where direct sunlight can be an issue.. might be too much work for the little return though
Add Pandora to play/pause/next & add song info, so that song/artist information is shown, when playing Pandora. These currently do not work. It would be great to just display the EQ with these features working.
