First at all thanks for your WB. It looks nice.
As you raised my awareness with this post (I have look into your blog, which linked the blog of another guy that also has done a collection of scripts), I would like to let you know that I would like to see a sheet metal Workbench in FC Master (not just as a plug-in).
I do not know if there are some community plans I am not aware of to develop one separately. I think that having an "official" sheet metal WB, apart from enriching the variety of tools FC has, would also join together this and that another developer, so that the community can profit from small contributions from different parties.
What do you think about this, guys?
