That's a very good thing.  Let's hope they revamp the UI as well.  That's my biggest single gripe with Poser, the UI (well, that and by extension the library).  There's LOTS wrong with it, but the biggie is wasted space.  I really hope they revamp the UI with an eye toward legibility and space economy.

I'm not griping, btw.  :)  Real undo, adding new cameras, and improved preview have me in anticipation mode.  When's this ship supposed to sail, btw?
