>I'm very happy just to get hidden line removal

Me too!
But it would also be a huge help if I don't have to manually pick a lot of silhouette lines to generate a 2-line-weight illustration. Even more when it's not that hard to program. Michael asked questions specifically about it. So he sees a need for it. I'm confidend he will keep MoI simple. I'm currently using C4Ds Sketch & Toon. It's slow, complex and it's not vector. If I can do it with MoI and Illustrator...


>overkill export options

I agree it's overkill to set line weights on export. It's easy enough to do in Illustrator.
So something like this would be sufficient:

Separate out:
[ ] Silhouettes : [ ] to layer
[ ] Outlines : [ ] to layer
[ ] Hidden lines : [ ] to layer

or even simpler

Separate out:
[ ] Silhouettes
[ ] Outlines : [ ] to layer
[ ] Hidden lines

Just give Silhouettes and Outlines a thicker outline please so there is an instant impression.
