Implementing that (and my later use of graphics and epigraphs for section breaks (though I've dropped the narrative elements), I implement SOL's section command { p}, but also include the other elements in the main chapter, including the section headers so the readers won't miss the section groupings.
To make it clear: I convert downloaded zips to my own html library with my own css. The SOL formatting is preserved as far as possible which is almost completely. I have several reasons for doing this: css formatting to my personal liking, reading off-line, formatting for all devices, add covers, add different themes, add choice of fonts, add font size selection, add pictures or maps where I feel I need them, and more. over time it has become quite a project where I even keep lists of author aliases, deceased/retired dates, US-to-metric converters, and a list of source links. I even have author profiles for a lot of authors with biographies, pictures, and links to their site. I created the same 'profiles' for universes. It started as a hobby project to better learn html, css, and javascript but it got a little out of hand and it grew with all sorts of nifty little extras ;)
You're one of the few authors that make the effort to add covers, graphics, and other extras which is greatly appreciated. Ernest is another author that takes great care of formatting and adding floorplans etc.
The section headers problem is now solved and from the original post of this thread I understand that the possibility for section notes are added. As you mentioned you used section headers containing locations which is exactly why I asked for the section names to be included in the chapters. It's important information. For my converted library I even extended it so that the section names are included in every chapter, not just the first chapter of a new section. We're very fortunate that SOL offers the very best formatting I have seen compared to other story sites.
