EDIT A SHAPE - AFTER You Have Clicked "APPLY" ? .... Seems you cannot do this

One of the scary things in Modeler, is that once you click "apply" or the "spacebar" you cannot go back and do any real edits on a shape. You really must know what you want to do before you commit those changes. This may really deter many from using this program.  One mistake and 20 minutes of work can go down the drain.  So many things missing from this program I've come to realize, and I realize now this is perhaps why so many are just using Blender which is 100% free.  I will continue to have faith in Adobe, but there is just zero activity on this forum, and this shows lack of interest from those who have tried 3D Modeler.  I've posted a bunch of questions, and no answers, not even from Adobe employees themselves, which is really discouraging.  I get this sinking feeling that Adobe is going to stop updates on parts of the 3D Substance lineup for some reason....
