Unless I am totally missing something, I do not see an option for a numerically controlled scaling tool. I would like to see one added for finer control.
It would be nice if there was some kind of "hinting" or UI option in addition to double-click. How many things in S3D are like this, where nobody would find them unless someone told you how to? Right click would be a standard UI practice.
