For all interested,
I’m working on a upgrade of the whole system. Something like a ModelingSuite, with not only Extrude, but also Taper, Curve, Bend, Flatten/Splice, MeshA plus MeshB and MeshA minus meshB.

But I want to publish it with as few as possible bugs and as practical as possible. So stay tuned and you will be rewarded. 
Greetings, EddyL
