I like the new chapter sections for highlights. But I wonder if it is possible to prepend the name of the parent sections to the name, or (even better) have the chapters nested within collapsible parent sections - as is the case with the Table of Contents.
Here's a few highlights that I have from one book that is organized into 4 Parts, each with dozens of chapters. Other than the order there's no indication to know which Part the chapter is from.
