It would be great to have the ability to expand the data for the library statistics to show more than the top 5. Without getting into custom reports and make it too complicated, a minimum of 10 or ideally 20 would be more useful than the current top 5 which is kind of limited. I guess it all depends of personal preferences and what users actually do with that feature, and this why an option to select the top XX that would be reasonable to each user would be perfect.
Also an option to export the information either in html or pdf would be very nice.
