Currently changing what device studio is emulating while playing is disabled. This makes it so testing a specific part of a game on a large number of devices/screen sizes takes much longer than it should.
Making it so I can change what device studio emulates while the game is running would speed up development
Support, I currently use this feature for grabbing temporary game icons so I can identify my game until the fully 3D-modelled version is complete, it is a nightmare having to switch between my game-icon and normal playthrough emulators.
