Something that I hugely wish: A library in your home. In DD, I love the number of books, but it's a shame that you need to pick up the book and place it yourself in the library of your choice. And once placed, if you need to re-read a specific book, you need to reread a lot until you find it
So my idea: you still need to pick the books (or steal them), but once in your home, you can put all your books in the library with a single button. And the library shows the list of book that you have discover, and read them. Though, you still can take the books (By example: A treasure map: To avoid the need to return to your home, you take the book with you.)
PS: Maybe all of this is already include with the notebook.
