@pholy - that's probably what I'll do going forward - but at the moment I have plenty of books in mobi only format - as do many other authors !
@JSWolf - I'm talking non-fiction here - indents look dreadful - particularly when combined with sub-heads and bullets! The standard of no indent for NF is a standard for very good reason.
I don't have word (I do have openoffice which formats slightly differently) - but I don't see why I would go back to word - for one thing it will add unnecssary <p? tags around the <li> items which have to be removed again.
I've never found a need for Sigil- it seemed overly complex in comparison to notepad++ What benefit does it offer?
