To make things more interesting you could colour code books by genre and add icons to columns.
I use icons to tell which books are on whose reader when they are not plugged in, which books to upload next, which books have been read and if the book is an audiobook (not stored in Calibre but referenced in the database).
Books in a series are one colour, one off books another. The possibilities are endless and your daughter could choose which icons/colours to use.
Part of my library is shown in the attachment as an example. Hope this gives you a few ideas.
