Allow keyframing using draggers
The workaround for keyframes (using the transform behavior) being used in draggers is good. The problem I run into is now both objects marked (like the elbows) are rotating using the transform tool (because ARM IK is set at the body level). Posing arms would be a lot easier with the ability to set keyframes for arms or wherever draggers are.

This is astonishing to me, that this feature is not available yet! Without this, I'll never be able to do a bit more complex animations. For instance, I want to let the character stand up, and want to keyframe every dragger.
