Handy tool for working with bone constraints

Click to select a bone. With a bone selected, Shift+Click to set the Angle Control bone, Ctrl+Click to set the Scale Control bone, Alt+Click to set the Position Control bone.

The script also shows you the constraints as color-coded arrows. The green arrow is Angle, the red one is Scale, and the blue one is Position.

The following scripts will also be included in the downloaded ZIP:
