Re: How to create a book from multiple collections?
The current behavior is quite terrible. A book is limited to one collection and you can only add photos to your book from one collection. After you save the book and you want to add photos from another collection, you cannot just click on the other collection and drag photos to your existing book, because clicking on another collection creates a new book and re-populates all pages with pictures only from that other collection. This is frustrating. Instead you have to open the other collection in library module, drag the photos to the saved book collection, go to the book collection and add photos from there. Organizing photos this way is really tedious, especially if you want to have chapters in your book. It completely eliminates the organization of photos in collections for a book, e.g. for different chapters of your book.
Feature request: There should be an option to switch between collections, while a given saved book is and remains open. For example when I organize photos for different chapters of a photo book in different collections of a collection set. When I am working on a book, I would like to be able to click on one collection, see the photos in the bottom filmstrip, and drag and drop photos to the existing open book that I am working on. Then click on another collection - while the existing book that I am working on remains open and unchanged - and choose photos from that other collection and drag them to the book. This would allow for much better organization of photos in a book.
