I'd like to see better EPUB3 support, particularly the ability to read series title/index from the packaging file (see
http://idpf.org/epub/30/spec/epub30-...itles-examples). It would be a nice way to set series data for sideloaded books and could be used the same way whenever Kobo starts pushing out EPUB3 books.
Bonus points if it also reads these tags from an EPUB2 packaging file
