Another question, related to the page: Should a
add_chapter_numbers:toconly under a [storyUrl] section override a
strip_chapter_numbers under [defaults]? (Kobo Utilities glitches when updating a ToC that has two items with the same title, which may happen if a user removes the numbers.)
When I tested it it didn't seem to work but I may have made a mistake.
EDIT: User error, but not the kind I was thinking of -- I mixed up the ## author - title comments on two stories with identical tweaks and was testing with the wrong one.
ANOTHER EDIT: Confirmed to work, so added to page.
