A few cosmetic changes I'd like to add:

In the library (which takes up a lot of space), vertical scroll bar on the left instead of the right.  I have to use the horizontal scroll bar to get to the veritcal.  Also a collapsible button like in earlier versions.  I know I can close it or undock it, but reopening it is more steps than necessary.

The Memory Dots:  take up too much space as well by still being a row of three.  Why can't these all be on one line?  There are only nine of them.

All that space after the "room" tabs.  Why can't we put things up there like the library and other tools that would be available in other rooms?  This would be a real space saver!

More flexibility in docking like putting side by side.

Two entirely different questions:

How do I get my old Python scripts into Poser8?  I tried copying them over to their respective folders and Poser crashed when I tried to load one (DAZ/Mac's Room Creator Quick Pose, which I find very useful for moving any object).

I already have PhilC's Wardrobe Wizard2.  Do I need the one that came with P8?  I use the external version anyway because it's faster.
