This would let you select one or more bodies or faces and generate essentially a tight, shrink wrapped plastic boundary that surrounds them.
Ideally this would be implemented as a convex hull but with parameters to allow the user to specify clearances around objects, maximum bend radius to avoid sharp corners, and a way to turn the corners to control points for a spline or NURBS like organic surface.
Very useful for designing shells and fairings and the such.
Please vote for it this time, people. Literally costs you nothing.
