Some betas ago, quite effective export of the text styles was eventually imlemented and works well for ‘body text’ and its parts. However, there seems to be no chance for a customer to assign any style to a footnote when exporting to .RTF or .ODT. You can just get a ‘Normal’ style, the same as for the other ‘No Style’ paragraphs. I see it as a serious flaw in both practical and, even more, conceptual respect.
Practically, most of probable an author will want to give their footnotes some special format when working on the manuscript in Word, or WordPerfect, or Libre Office, or whatever text processor. In Libre Office, I have to manually assign a special Footnote style to each footnote paragraph, and, what even worse, when I do it, there is considerable risk to lose some numerous italics omnipresent in references—they are ‘direct formatting’ and quite fragile in comparison with (character) styles.
Conceptually, it is just strange for a user to easily export quotations, and headers, and any other part of the ‘body text’ with a style tag attached, but to be unable to do the same for such a special text structure as a footnote. Important notion: it just looks like a remnant of the old, out-of-dated approach to the styles (as sort of formatting shortcuts) from 1.x (2.x for MacOS) version.
Just in case, I tried to frame the problem earlier this month: [Suggestion] Almost a Bug: A couple of Essential Compile Options Missed. I am afraid I was too wordy and not convincing enough—there was no reaction from developers. Glad that there are some other people to be interested in this topic.
Just in case, I am still not sure this important matter is for the scrivener ‘wish list’.
