If someone's WeWrite pages grow extensive enough, it might be appropriate to print the writings in a book format, instead of the default article format.
There could be a few different approaches to structuring books.
Pages as chapters, Sections as chapter sub-sections, collection of pages as the entire book
Page as a book, sections as chapters
Approach #1 is probably the best in terms of ensuring that the content is readable on WeWrite. For a single page to be an entire book might be rather cumbersome on the app. However, if we implement scroll position memory (like in Kindle or Apple Books) then maybe the second approach could be more viable.
