I wanted to voice my frustration with the Library Widow. When I open the window, all of the libraries are expanded, which it makes it very hard to read an find the library that I want. I usually go through and close all the expansions, so that I can find the library that I want. The next time I open the window they are all expanded again. This is very frustrating, and I would prefer that they start closed and then I can expand the ones I would like to explore.
This might be a Mac issue.
