The main issue though is that the default settings are such that the actual section name (whether we call it a chapter, part, subsection or fig leaf) is used in the ToC (understandably). If you have things set up to print a heading with “Chapter 1” after a section or page break, then that is what the ToC will print. It is what most people would want to see, of course.
- If you want it to print something else in both places, not just the ToC, then use a different Section Layout for these headings.
- If you want something less orthodox, where the chapter itself prints “Chapter 1” above the text, but the ToC prints “Fig Leaf One: Name of Folder”, then you’ll have to not rely upon default settings, which overwrite links, or update them to match what you pick for the Section Layout. Again, it’s what most people would want, if a cross-reference to “Fig Leaf” is not meant ot be something the reader sees, and that section prints “Chapter 24”, then you wouldn’t want “Fig Leaf” printed anywhere in the text. But you can turn that off, or change how it works, as described in the link.
