We have just released a new version of botcha for Rhino! You can get it from the package manager, from our website or food4rhino. This new release include some experimental features for lace creation and more!
If you want to get a quick introduction of the plugin and how to use it you can check out this tutorial that goes over the basic functionality, more will come in the near future. If you have any question please do reach out to us!
We are looking at other plugins such as XNurbs, Bongo and similar to determine what is the appropriate pricing for the amount of utility that we are providing. Hope this helps
I am not 100% sure what you mean with “support”, we have already support for uv editing, remapping for SubD. We have yet to refine support for the modifiers that behaves a bit weirdly at the moment (on subs and NURBS surf)
