Something I really love about iClone is it's spring system, it's fast, efficient and fluid.

But it would be nice to see some love show towards the system, things such as :
- A way to edit the blending (from within 3DXchange) between the sprung and rigid areas of a spring bone so that we can control which areas are effected a lot better.
- IK for spring bones.
- Volume setting for spring bones so that each one can have a different weight.

My mind over-loads when I think of the possibilities if such features and enhancements were added.
