I can add shear and twist without too much problem. But the royal way to all these deformations is definitely Sketchy FFD.

I Know FFD is very powerful for deformation tool, but its not as fast and easy to use as your Taper Deformation Script.
with FFD it is very hard to do an accurate bend or twist, also you canot deform Nested Components or Grups, and you canot align the deformation as easy as you can do it with Taper deformation in your ruby.

Thxs a lot Fred for this plugin, your ruby scripts are amazing.
Do you think you could add more transformations to it, like bend, twist, Bulge
Maibe for a comercial plugin?
