I've searched the discussion archive a bit, and I see references to various external tools to massage a single HTML file produced by AD into multiple files.
Is there a native way these days to do this? E.g. some simple variable(s) / attributes to set?
See this example - it's probably 100 pp plus in PDF form. With all the CSS, it's a big load in a browser, when people generally want to just see one chapter.
I don't see any way in the current user manual to do this.
