Typing in devices for each scene is labour intensive, why not allow us to select an area then a toggle to ignore/include each device in that area?
Copying Scenes - if the above is not possible, copy the scene to a new scene from within the UI (I appreciate you can do this in the YAML, but hey, everyone likes a UI!)
Really pleased to see the addition of Scenes, HA just keeps getting better and better, keep up the good work
