All from a game making perpective:
1. A way to remove mesh parts like toes for instance, or turn to boots or shoes or something.
2. A higher and lower poly mesh, for normal mapping and for game models (maybe 6000 polys).
3. A bone export without the model, and model export without the bones.
4. Weight verts to bones, weight painting.
Man if you added texture painting and sculpting with the fantasy targets, you'd have the
ultimate charactor creator.
Just ideas, I love this program
