I have been thinking about adding generators for the basic building blocks like walls, edges, ... That would probably pretty easy to do - although not that exciting. I thought that might be most interesting for the Inkscape plug-in. Then you could build your own, one of project from those primitives without bothering with Python and programming.
But as we still don't have a way to get Boxes.py running on Windows I wonder how many people actually use the Inkscape plug-in at all. Well, I don't...
Otoh having those primitives available might be interesting for the web UI, too. Not as convenient as one needs to go through all the Save as, Open, Cut and Paste hoops. But may be some people are doing this anyway but have to look through the generators to find the parts they need.
So the question to everyone: Are you using the Inkscape plug-in and would you be interested in generators for simple parts? Please comment below!
