In the previous version of bones, selecting 2 or more bones can achieve automatic ik.
It is very fast to make animation. The new version of kinefx suggests that it also be added.
In addition, the model of the previous version is highlighted,
and the method of clicking on the bones is also very good.
I hope that kinefx will also be added,
and more operations on mirroring,
such as weight, animation, and the image operation of the manipulator, will be added
