A: No. The add-on only adds and manages the Damped Track constraints that make parent bones follow their children — it doesn't generate motion at the chain's tip by itself. If the tip bone never moves (no simulation, no baked animation, no keyframes), you won't see any jiggle after adding constraints. Pair it with baked cloth/soft-body simulation, hair particles converted to bones, manual keyframes, or another physics add-on
