When doing sky replacements, I find myself always throwing the Colour Adjustment and Edge Lighting sliders all the way left so that the green cast is removed and the sky blends well. I also almost always set the Brightness to +50.
Wouldn't it be convenient for the sliders to just stay where you leave them? (Make them sticky) or create a preset with that sky?
(When I create an action, it doesn't remember my settings)
