Rigging tool. Specifically what was said already a couple of times.

More morph tool brush options.

Grouping tool options (select loop, select ring.....) 

Completely customizable UI (with return to default of course) for a better workflow.

And an auto save option which is on by default (which can be turned off of course)so when poser does crash for whatever reason, you can just reload that last scene/item/character instead of doing it all over again.
