I would say the export functions are among the weaknesses of Quoll. You can export to HTML, docx and epub, with the only notable configurable option the selection of the chapters (and character notes etc) that should be included in the export. For epubs you can also configure author name and ISBN.

The quality of the exports is not that great. The HTML looks good for printing, but is a pain to read on screen. The epub looks good, except that it doesn't display chapter headings. The docx has 8 newlines between paragraphs when I open it in OpenOffice. I don't have a MS Word on hand right now to check whose fault that is, but it's unfortunate since I would probably go via docx to pdf.
