Motion Path Pro is a Blender add-on by Hamdi-Amer built around a technique for updating motion paths in real time. It works with any kind of object, including empties, cameras, meshes, and bones. The developer describes it as a way to make polishing animation faster, simpler, and easier.

The add-on has been downloaded more than 24,000 times from the Blender extensions library, and a tutorial video is available. It's listed as free in this catalog; check the developer's page for current licensing.
