I don't understand why independent angle in Bone Constrain is not animatable.
I have requested a new feature for the animation keyframe or animation for independent angle for long time; As I remember, maybe before the a few last updated version. I think Independent Angle should be animated, and I hope the developer team is working on it for the next updates too.

Hi,
I'm not sure what you mean. I animate Independent Angle all the time, typically for foot setups. For example...

In the above, I'm using Independent Angle to keep the foot bone level with the ground, but I'm also keyframing the rotation of the bone after the foot is lifted off the ground.
What Independent Angle does is it puts a bone's rotation into world space, so it effectively bypasses the rotation of parent bones. It should not prevent you from keyframing the bone.
Are you not seeing this behavior?

Oh, wait! I know what meant: Independent Angle's on/off state should be keyframeable. Yes, I agree with you! I've asked for this option myself. Sorry, it was early in the morning and I had not had my coffee yet.
You can sort of work around this limitation using Vitruvian Bones, but having a keyframeable On/Off option would be easier and very useful, especially when used in a Smart Bone.

Yeah, keyframeable Independent Angle something I can really use, but got used to not having it, and almost forgot about it.
The other feature I still want is keyframeable visibility for bones. I use Vitruvian Bones as a workaround for this, too, but it would be simpler if I could keyframe a bone's visibility directly.
Hopefully, we'll see these features someday! They would be super helpful!
