Call me a luddite, but I'd love to have a button along the top of the touchscreen that turns the screen blank. Sometimes I don't want to see the data, music, or image behind me, especially at night. Presently, I have to go into the Easter Eggs, bring up a sketch pad, and fill the screen with black. How about a little satellite icon (called "space"?) that toggles the touchscreen on and off? I tried messaging @elonmusk, but I think he's busy with other stuff, so I'm starting a crowd campaign here. Let's refine the idea and try to get it implemented...
