"Live Feedback" and all lights on a single colour picker

It would be REALLY great to have “Live Feedback” on the colour picker!! Just the same way it works in the Philips Hue app. Maybe even group all the lights of a Scene, Reaction, Animation etc. on to a single colour picker wheel (like in the Hue app). That would cut out a lot of steps making the whole process MUCH faster and easier.

Thanks!
