It’s great that we can now add natural dividers within the page structure but it would be even better if you could create hierarchies or expandable sections within the pages section.
For example, if you had a file that consisted of designs, research and misc for example, you may want multiple pages like this:
Designs
Desktop
Mobile webapp
iOS
Research
For testing
Competitor analysis
Market
Misc
Cover
Background information
This would provide a page hierarchy that would be much easier to use and more focussed, especially as a file grows over time.
