Folders and Nested collections.

I am just testing Capacities, I like the backlinks and flexibility and multiple tags, however why NOT allow the folders anyway. Say I am working on saving stuff from a book. I want to create a collection with the Book name, then have a NESTED page inside with the chapter name and a Nested page inside with the content. And I want to collapse it all so that on the side bar I only have 1 collection with the BOOK's title for cleanliness of the view. The book has hundreds of chapters and pages inside. Without Nesting and collapsing into each other I will end up having EITHER a ton of UNSORTED pages within a Collection (with the book's name) - without the ability of sorting them into a chapter or visa versa tons of Collections under PAGES with the book chapters (and pages inside those chapters) But these may not be the only collections under PAGES, this way if each chapter is a collection and I can't nest things ( as folders ) i will end up with a million of the collections under PAGES of million of objects ( if I create a book as an object. Everything you have is grate but why take away features that work say in Notion, and let people that want more have more like ho capacity is structured. Why not have the BEST of BOTH worlds...
