I still prefer P3do Explorer.   Library items are displayed horizontally making best use of space.   Upon selection you can see the path for Geometries and Textures should you wish to export something.   Double-clicking it will open it in Poser.   Best of all, it's free and has been for many years now but constantly developing with lots of new features being added.   There's an .rsr to .png converter and mass renamer that always come in handy as well. Check out the screenshots to see how customizable the interface is. 

Although I appreciate the changes made to Poser 8's library after people's feedback, I'm much more comfortable with P3do :)
