Ok, spend some time playing around with twinery
Take a backup of your story then:
- Add "Config.passages.nobr = true;" to the stories javascript
- Use search and replace, click use regex and put "\n\n " in the find box, and in the replace box do
<p>
With the empty line before and a linebreak after the <p> - Add the following to the stylesheet
#passages p {
margin-top: 2em;
}
If all goes correct it should be converted to use <p> instead, and you can play around with the spacing. It might be simpler to rerun the search and replace instead of manually adding in <p> in new passages.
