Ready to release a demo to channel. Just had some questions.

I would like to upload a demo to the release channel for testing. Everything seems to work great, and I've followed build instructions. Do I need to get rid of the default unity windows that asks for resolution before uploading the build? Launching from my library is a pain. 

Also, what do most of you use to let users exit the game. Wrist UI? Or maybe a curved UI popup?
