Bone Trajectory Tool

A tool that displays the movement trajectories of bones and bipeds in the viewport as lines, sample points, and frame numbers, so you can see the animation flow at a glance. Manage multiple objects in a tracking list, and batch-change key tangents to Smooth, Linear, Step, Auto, Fast, Slow, or Flat over a chosen range. Position-error-based key simplification (decimate) plus previous/next key and frame navigation let you quickly clean up heavy animation data.
