Quote - 4.)  And also on the GUI, I wish that any docked libraries could be slid closed and opened with a click like in P7.

I already asked for this, and was told to use Ctrl-Shift-B to toggle the library, which works indeed just fine.

Quote - 5.) The material room GUI seems like it's not quite done.  I've seen people talking about the titles running off the nodes, which I've experienced as well.  However many times, Poser 8 crashes when I enter the material room. Are others experiencing this?

No, not this, but I had it leave when I tried to add a Blinn node. Restarted, reloaded the scene and this time it worked just fine, so apparently it's random.

Quote - 8.)  P7 scenes open without a hitch, and render immediately.  Whew, and thanks!

Do your P7 scenes load in the right dimensions? Mine load in whatever aspect ratio the last preview window was in, even if it's undocked, which is an obvious bug. I expect my scenes to load just like I had saved them.  :-/
