In an AV scene, you can now select only one device. If you use a projector and a corresponding electric projector screen (that goes down when watching and up when finished), you have to choose one of them, while you want both to action.

 I tried to create a Home Scene, but that doesn't allow you to select the project screen either.

This would allow to keep one remote control only, one not at least two now - which was the purpose of Sevenhugs' one.
