I would love if the group brightness would change when any children changed, so I can respond to outside adjustments of the group. Today when children change the main light remains at the previously set brightness.
This could be a configurable option, I'm not sure what the total brightness should be or how it would be determined according to the change. This is mostly interesting for me in trying to get Lightener to work well with adaptive brightness. (thread is here basnijholt/adaptive-lighting#978)
