Add Extra Face Bones: In Genesis 3 and 8 characters, expressions are poses for bones in the facial rig. The face bones then become driven by rig properties and cannot be posed freely. This button add an extra layer of face bones which can be posed freely on top of the driven bones. Deprecated in version 1.6: Use Make All Bones Poseable after the morphs have been loaded instead.
Change Prefix To Suffix: Change bones names from the prefix notation used by DAZ Studio (lShldr, rShldr) to suffix notation necessary for using Blender's symmetry tools (shldr.L, shldr.R).
Change Suffix To Prefix: Change bones names back from suffix notation (shldr.L, shldr.R) to prefix notation used by DAZ Studio (lShldr, rShldr). Necessary to convert rig to MHX or Rigify.
Add IK Goals: Make selected bones into an IK chain and create an IK target.
Add Winders: Create a winder bone that controls a chain of bones.
