 ## Planned Features
 
-Wishlist:
-
-1. Ragdoll and physics integration (inititally `bevy_xpbd`, possibly rapier
-   later):
-   1. Using a bone mask to specify which bones are kinematically driven, and
-      which bones are simulated (i.e. _ragdolled_)
-   1. Pose matching with joint motors (pending on joint motors being implemented
-      in `bevy_xpbd`, currently WIP)
-1. FABRIK node (?).
+1. Ragdoll "pose following" modes, where a simulated ragdoll bones try to match
+   a target pose using physical forces:
+   - _Absolute_ matching mode, where the world space position/rotation of the
+     target bone is tracked and use as an anchor for a spring force on the
+     ragdoll bone.
+   - _Relative_ matching mode, where the ragdoll bone tries to match the
+     target's position/rotation relative to its parent bone. We may need joint
+     motors support on Avian to implement this mode properly.
