A store environment to walk around in while browsing games (much like Home)
I've noticed the in-VR store has been reduced to a simple Dash menu, which is convenient but not as exciting.
A good VR approach would be to expand on the previous implementation of the store with free locomotion and multiplayer so people can actually wander around the place and browse games and apps with friends. Much like how Home went from a stationary 1.0 environment to a free locomotion 2.0 experience, the Store could have a 2.0 update in the same vein. It would make shopping in VR a lot more fun.
