It would be really cool to be able to alter the angle of the world so that one can recline/lay on your back but still be able to function in VR. Sometimes I come home from work and my back hurts. I'd love to pop into VR to unwind. So far I can basically do this in one app "Bigscreen" and that's great for movies and some desktop work, but plenty of gamepad games in VR would benefit from this option.
