Apart from the fact that class A surfacing is a black art, it isn't a magical thing that the tools do for you. Even Alias with it's tons of surfacing tools requires a tremendous amount of effort from the user to help the software do its thing. I don't thing this should be an area that MoI should be focused at. OK, maybe some diagnostic shading/materials and a bit more robust fillet/blending tools are welcome.

On the other hand I believe that MoI lacks a proper industry standard layer system which will help with organization, selection and geometry visualization. It kinda works as it is with the styles, but I really wish there was a treeview control with drag & drop support and the concept of an "active" layer. In fact I experimented by using some javascript treeview widgets and treated styles as layers, but I ended-up abandoning my effort because it was a hacky way and nowhere near as robust as I'd wanted it to be.

The other thing would be more of MoI's internals exposed to scripting and proper documentation for it. The community has already done wonders with so little to work with. It's what every major software has done because it allows anyone to have a custom workflow, it lets you do any non-standard stuff you can imagine, and frees the developer from having to fulfill every little request. Not to mention that a powerful API will attract even more knowledgeable people to do even more complex plugins.
