The new question Bone to mesh - convert is pretty much a duplicate of Convert bones to meshes. The new question is asking for something a little bit different, but it appears @lemon anticipated that as there is commented out code in the original answer to do what the new user wants.
My question has two parts:
The original answer is for Blender 2.79 won't run under 2.8x. Should I make the edits to the original answer's script, add a second script in the original answer, or put the updated script in the new question?
I think a GUI to ask about bones shape would be a good improvement to the original script. If I do add a GUI, Should I make the edits to the original answer's script, add a second script in the original answer, or put the updated script in the new question?
