ive made a new addon with more choices of algorithms for smoothing. It includes vertex group masked smoothing, constrained smoothing along custom,object or world axes, options for non-manifold handling and vertex normal compensation (like a per vertex Alt-S shrink flatten).

when I get a moment I’ll try to integrate shrinkwrapping like fabian fricke’s relax add-on into the choices of normal compensation.
comments, suggestions and bugs gladly received!
