Would like the option to group a collection of pages within a notebook, and collapse / expand them to make larger notebooks easier to navigate.

Don’t want to create nested folders as this involves too much clicking around.

At the moment I create section heading pages and tag them as favourites, the use favourites view as a type of table of contents page like a book.

Would be better though if from the outline view you could group and collapse pages to make it easier to scroll through the groups, then select them to see the pages in sections to see the pages within.
