I'd like to be able to selected an IK chain and reduce strength with a percentage slider.
Users should have additional options such as the ability to make the strength global across all the joints in the hierarchy or a falloff starting at the toes and ending at upper arm or clavicle or the reverse.
****The curve editor preset could help define this with a mode for skin weights across the entire hierarchy **** this way it would save users time rather than modifying each joint.

Some creatures made will have soft movement/influence by default such as slugs etc
