I couldn't agree more with this. I have actually been looking at writing a CAM program that uses OpenSCAD (and perhaps the python bindings to it) in order to generate gcode for machining. It would work great for me, but probably less so for the guys in the shop. Representing the OpenSCAD code as a tree you can fairly readily edit next to the renderer would help. Being able to click on something and have it pull up all the relevant nodes regarding that element for editing would be a huge help. Then of course the next step is being able to drag and get context menus for things like bolt circles or other kinds of symmetry. FreeCAD doesn't really cut it when it comes to trying to do these kinds of things, in my opinion.
