If I want to manually control a bone that has a spring this is what I have to do:

Select Avatar
Edit in 3DXchange
Edit Spring
Find bone in question
Disable spring
Apply to iClone

When it would be easier and much more convenient to Deactivate a spring bone directly in the Spring Modify box (see attachment)

Have them all Activated by default so it all works as it originally does but give me the option of turning them off per each bone to be able to manipulate the bones with motion layer keyframes. If a bone is Activated again all keyframes for the spring bone is ignored.
