A reselect command like Photoshop has would be great. After smoothing only a select part of a mesh I'd like to see what that section looks like without being the solid pink color. Then if it needs further smoothing I can reselect the same points and proceed with the smoothing. Or if after spending time carefully selecting specific points, a sneeze or something might make me mis click resulting in me loosing all those points and I have to start all over.
