So far as the Compiler has been or at least next to be ready for release, any proposal about missed options in it sounds a little belated. I do believe, however, that the following matter is not only practically, but (even more) conceptually important, and in a way should be considered as a bug.
I must say here, I rarely use the Compiler and almost never its settings. I do not need much from it because what I do in Scrivener is mostly organizing my sources, writing, editing, and moving fragments. When writing is done, all I need is just a correct final .ODT-file. (Just in case, I do not think I am the only one with this approach.)
The ‘correct’ means that all the parts of the text are in place, including ‘body’, quotes, headers, etc., and the style structure is preserved. The latter is essential: each style is first of all a functional part of the text (quotation block, or emphasized word, etc.) and only then a collection of some typeface attributes.
In practice, it means I can open my file in LibreOffice, load previously defined set of styles from other .odt-file or template, and the document would be perfectly re-formatted—in just a couple of mouse clicks.
The idea of ‘No Style’ paragraphs still seems doubtful in this context, but it’s not a problem at all: the ‘unstyled’ paragraphs end as ‘Normal’ style in LibreOffice: there is some text and its specific style. The real problem I have just found is that all footnotes get the same ‘Normal’ style as the main text, which is obviously incorrect, and I found no option to correct it.
So (1): While there is a special tab for ‘Footnotes and Comments’ options, I am sure the option to assign all footnotes (and probably endnotes) a special style—built-in or, better, user-defined—is obvious necessity and hopefully not a fundamental technical problem.
In direct connection with that is (2): in ‘Transformations’ tab there is equally obvious lack of converting all italics (optionally underlines too) to ‘em’ (or maybe some user-defined) font style. It is actually of great importance because you can lost all your italics, and underlines, and any other ‘direct formatting’ when you apply a command like ‘Clear Direct Formatting’ to a paragraph in a word-processor (and, by the way, layout system like InDesign).
I think it is just important enough and (I hope) not too expensive in technical terms—so decided to place it here.
Just in case—I am not sure the points have never been discussed on the forum before–if so, my sincere apologies for this unnecessary long-read and repetition.
