The Brightness slider, the Color Slider and the Add Scene Button take up way too much screen space when viewing a Bulb group. It would save space (and be more consistent with other product type groups) if these options were moved to the Bulb group settings accessed by the Gear icon at the top right of the Bulb Group.
it’s possible I am misunderstanding what you were saying but, Seems to me it’s good the way it is, I don’t really want it extra step to get to the bulb group settings
