Can't say how much use it would be, But maybe using soft selections to make gradients in PS? Could be useful for receding geometry that you want to add some addition AO to, or maybe soft select all the verts towards the bottom of a model and create a gradient from that. Instead of going around shell by shell making non uniform gradients.
just a thought
You got something cool for faces, something cool for edges, Might figure something else for vert selection.
The only way it could get any better is if you made it for Max
