More templates for the material room.  I have seen wonderful work done here in the forums just going and buying some of the best work like the wet & wound work from skinvue or the mud node work that was done here recently and some others and offering it in the package would make a nice addition.

But again, I want to see improvements in the animation capabilities spacially involving coreography of movement of two figures interacting--circular IK, keyable parenting.

Also softbody dynamics, a Particle Illusion new tab for special effects and Poser Physics.
