Allow deselecting all lights at once
Great app! I use it a lot because it's the simplest way to control the lights! One slight change would make it even better though...
I often want to use the app to quickly change one or two lights. However, to do this I need to manually deselect all other lights one by one.
It would be great if you could update the behavior of the "all lights" button so that when the "all lights" button is pressed when all lights are selected it deselects all lights.
