Better Smooth Brush Algorithm

I think one of the biggest features that Blender needs is an algorithm for the smooth brush that acts the same as the smooth brush in ZBrush. I know that there are settings that can be tweaked, but I've found no settings so far that feel anywhere near as intuitive as ZBrush's. ZB's smooth allows volume preservation and a sort of "blurring" the surface, where blender's flattens the surface, and even in "surface" mode the brush doesn't accumulate, so it takes an exorbitant amount of strokes to get anywhere near where you want. The Slide Relax smooth isn't quite as useful either, since organic sculptors use it in ZB to smooth pinched poles, but there's no smoother in Blender that gets close to removing poles. If Blender could update these brushes to account for these factors, I think the sculptor base would grow immensely. As it stands now, I have to use ZB to sculpt the way I want it to, and I can't really take sculpting in blender seriously. I want to change that.
