I would find the toggle useful because i am designing furniture for cnc production with various components that I need to get out in a flat state. So I have a 3d fully built model but I also have a version with all the components flat on the ground to make it easy to move the geometry into my CNC package.
Thanks for the quick and useful response!
(Are you interested in developing other plugins? I have one that I would like made and am willing to pay for. I don't know if you have seen the SliceForm plugin out there but I would like a version of that with the ability to make slices in a radial direction or to make slices that are perpendicular along a path.)
