Libra - organize your stuff, beautifully.

I just downloaded the program and quite satisfied with it, but there could be two things in the book area that could be added on. Firstly sorting by Author; right now there is sort by Creator which is okay but a bit repetitive as you have to change the authors name personally (i.e. George R.R. Martin to Martin, George R.R.) . Another setting which would be really good for all of the features would be custom sorting - dragging and dropping or some other form of putting the books in any configuration possible. The reason for this second one is I read many series of books and when I try to put them in the come up in screwed sequences.
