First, It would be cool if there was antithesis to the Smoothing Function, that turned up the Roughness downstream.
Second, unrelated, it may be cool to have a Edge Sharpness function to clouds. It's a little tricky playing with softness of PFs themselves, mixing tons etc. and I wonder if it could simply be function as part of the v3 supplied a grayscale colour/scalar map. Utilizing a soft noise PF like maybe Roughness 1 or 0, you could define where the edge is super sharp, or where it's super soft and anywhere between, applying it to whatever density is supplied.
