Auto Inertia

Hi,

In After Effects, one of the most commonly used expression is the amp expression. Applying it to for instance the scale property, gives a natural inertia to the scaling animation. I’ve searched around for a similar script for blender, and found AutoInertia.

I haven’t gotten it to work, and it seems quiet cumbersome to apply in blender anyway. Is it possible to create something similar to the amp expression for after effects? I know a lot of animators would love it. Or does something similar exist allready?
