Quote - OK, my wishes:

Add: 'Pin to Skin' function. Keeps piercings, earings and such in place on the skin when the figure is posed irrespective of morph or pose without resorting to simulation. Translations and rotation angles are read from the vertices bounding the facet the piercing was pinned to.

This is very similar to my above proposed clothing type.  This would help with so many things, from mustaches to jewelry.

I'm not a proponent of adding metaballs (though I do wish the weirdjuice plug-ins still worked) because it seems like those are mainly a modeling tool and I never thought Poser needed those.  What I would instead like would be some kind of mesh blending similar to metaballs.  It would be great if we could add horns, tails, extra limbs etc.  just by grouping them to an object and choosing to have them blended seamlessly at render time.  That would require some kind of dynamic meshing, or a render hack, so I'm not holding my breath for it.
