Allow user to save ebook to more than one bookshelf from the book info page
On the info page ("Table of Contents and more") for an ebook, users can click the button to save the ebook to the bookshelf, but it's not possible to save it to an additional bookshelf from that same page. Users can go to the bookshelf and then copy the ebook to an additional bookshelf; it would be more intuitive if this were possible on the ebook info page as well.

This would be more efficient because it's much more quicker and easier if you have a lot of different bookshelfs to share and you don't know exactly, in which bookshelf the title was put in at first
