Combine the functions of Delete Face, Unstitch, and Remove into one "Delete Face" feature. Currently the action of the delete face command is to try and patch the hole left by the deleted face. What I want like to see is an option to either patch the deleted faces, or actually delete them and turn the solid body into a surface body. As of now I have discovered that the "Un-stitch" feature will turn the solid into a surface, but then you have to go and "Remove" the surface bodies you don't want; an additional step and added feature(s) to the timeline (which is already pretty unmanageable).
