I would like to see the Environment Backplate brightness checkbox get replaced with a slider that gives 0-100% brightness control on the backplate.
I think this would allow more precise matching of the backplate to the model under various lighting conditions. The backplate of course can be altered in Photoshop, but when experimenting with lighting conditions inside KS, it would be nice to have this control of the backplate available.

+1!
And maybe saturation?
