Impression had Chapter support for long documents, whereby you could swap out non-current chapters for performance and manageability reasons (it's not very useful having one scrolling document 600 pages long or 600 thumbnails in a column). So this was a hierarchical way to manage book length documents.
To be honest, I'd not thought this through thoroughly. Perhaps I was thinking of something like OneNote where you can slide page titles in the navpane left and right to associate together (had to blur in image below for NDA reasons). Or maybe Word's navigation pane. Some way of visually seeing which pages are in what section in a document, or where section boundaries lie, presumably using the P&L gallery.
