The yw-cnv LibreOffice extension inserts scene titles as comments right at the scene beginnings, so you can easily navigate to them via the Navigator (F5).
It offers a choice of export variants as described in the
help pages. However, there's no option for a full manuscript with scene titles as headings, I'm afraid.
There is actually a solution with the
yw2html HTML converter. You can define HTML templates by yourself in order to design your export using almost every data stored in your yWriter project. You get an HTML document that can be loaded e,g, into LibreOffice Writer and converted into ODT or DOCX format (be sure to open it with
Writer, and not with the Web editor component). I guess, you can also use Word for further processing, if you aren't a LibreOffice user.
The yw2html distribution provides pre-made sample templates you can modify. In your case, i propose the "manuscript" template.
Just make two changes:
In chapter_template_html:
<h2>$Title</h2>
In scene_template_html:
<h3>$Title</h3>
<p>$SceneContent</p>
This will generate second level headings for the chapters and third level headings for the scenes.
Good luck,
Peter
