2. I see where the default styles are and I am happy with these
generally. However, as a libreoffice n00b, how do I create my own
style file that would be appropriate for the ODT exporter? It's not
so much about the creating of style files (although help in that
regard would not be sniffed at ;-) but about whether there is a list
of paragraph styles that can be customised somewhere?
The easiest way is now described in the manual: write your document in
Org, including all the sorts of stuff you might want to have styles
for, then export it to ODT, open it in LibreOffice, and tweak the
styles you find there. Because you exported it from Org, you can be
sure that the styles have the names the exporter uses. You can
customize any style, no limits.
LibreOffice's Styles and Formatting window is your friend (accessible
from the Format menu or from an icon usually at the far left of the
toolbar). It has tabbed lists of Paragraph, Character, Page, Frame and
List styles. Right-click on a style to modify it.
When your LibreOffice document looks like you want it to, simply save
it somewhere smart. The next time you export from Org, point
org-export-odt-styles-file to that file as your style template.
