Options
The options can be found below the bone chain list.
Multi Selection Chain Mode
Allows creating a bone chain from a given selection. This can be used to create a chain of arbitrary length.
Force Anim Rendering
Makes the animation play when manually moving through the timeline, making it possible to render the animation directly.
Clear After Bake
Makes it possible not to remove the bone chains after baking the animation
Warning
Don't forget to temporarily disable the simulation if you want to preview the result after baking if the chains weren't cleared. If not, the keyframes will interact with the simulation in a innacurate way.
Force Special Bake
Uses the addon's own baking operator instead of Blender's default.
Enable Simulation
Enable/Disable the simulation
