Truly useful for managing books! Fully featured way to create and manage a collection of books; from quickly populating with found information (or creating your own book details) to locating your book and tracking activity related to it. NOTE: I have the same problem as many others with cover graphics not showing in detail view (fine in list and edit). Oddly  vertical graphics are all missing but horizontal are fine. I worked with the polite developer a while back  but he couldn't resolve the issue. Android 6.0.1 Nexus 7.
