Insert quickly multiple notes from the same book

An important feature would be to be able to insert multiple notes from the same book, without having to select the book each time. One possibility would be to add a button at the end of the page that groups together all the notes of a book. A button like: "add a new note to this book". Another possibility, perhaps simpler, is that when you create a new note the system has already selected the last book to which the notes were added. Since many people read one book at a time, I think this would be a very useful feature.
