Be able to hide or archive a coloring book
Maybe there’s a coloring book you don’t like or want to see. For example, if you didn’t Iike autumn themed books, you could hide or archive coloring books that have that in there. Later on though, if you decided you want to have that coloring book back you can re-download it from “the cloud”.
