A few more feature requests, mostly prompted by my desire to have both D|S or Poser and PzDB visible at the same time:

1. Remember if previously opened maximized or in window
2. Remember if AutoGo was previously checked or unchecked (when you open it reverts to AutoGo)
3. "All Off" in addition to "All On" buttons for Categories/Keywords/Libraries
4. I may be missing something, but as I see it, if you're not using a Group you've created, the Keywords section is pretty useless -- it's blank if you're viewing all content, and in the pre-made groups it just includes various spellings/abbreviations for the figure in question.  If it auto-populated with all keywords for items found in your search, that would be fantastic -- you could then refine your search by unchecking keywords.  As it is now, I find it a waste of space most of the time.
5. An "Update All Libraries" option on the Import screen.
6. Options for the layout to be more useful in a smaller window:

a) ability to stack content and search windows vertically instead of horizontally,
b) ability to move the divider to shrink the search window and show more content
c) ability to disable the keyword window or auto-hide it when it's empty, or move it to the right of the Libraries window
d) ability to shrink the various buttons -- it's nice to have a great big Search button when you're starting, but once you're used to the program it takes up a lot of space.
e) The Create Poser Collections button is useless if you're using D|S or a pre-P7 version of Poser.  Even if you have P7, if you're using PzDB in place of the P7 content window, you don't need to create Poser collections.  It would be nice to have an option to hide it.
f) The PzDB import button is kind of useless, since the dropdown doesn't list the libraries, just the dates.  I use the Import screen to update my libraries anyway.
