well about the "own purposes", nemo, those function im looking for are really useful for everyone, not just for "me", if this plugin can be easier to use, its better for us, because actually its complicated to use, with all those math to put in place if we want something working.
also as a 3D modeler, i don't have the knowledge of coding functions we never see/use in a 3d software.
for a new user it's completly normal to ask a lot of questions about a new product and get the right answers.
if you don't ask questions before you buy a car, some day your'e going to have a bad surprise, and it's the same with a new software/plugin.
