If someone can suggest some markup code for paragraphs and scene breaks that would easily support such user choices (e.g. in EPUB), I would like to see it. Perhaps a new thread in the appropriate forum(s)?

What I have in mind would be a flag at the top (if conditionals are allowed):
IF user_is_spaced_out
THEN p-indent=0; p-bottom-margin=1em;
ELSE p-indent=2em; p-bottom-margin=0em;

IF user_is_splatted
THEN scene_break=" * * * * ";
ELSE IF user_is_squiggly
THEN scene_break="~ ~ ~";
ELSE scene_break=3em;

or commented out sections (ugh), or something like that.
