When I created my Cepheus Engine zine, I made the text in #LibreOffice, so I thought it'd be easy to make a #EPUB document out of it - just Export To EPUB and I'm done...
Only I'm not. LibreOffice EPUB export isn't very good. It doesn't export most of the headings at all.
So I tried a bunch of online converters until I found one that worked a little better.
The file still wasn't good, so I had to use Calibre's EPUB editor to mess about with the XHTML code directly.
It wasn't incredibly difficult, but it's weird this wasn't an completely automatic process.
