Need to find a doc' with proper footnotes (either end-of-page or pop-up), which is the ePub3 feature I'm really looking forward to, to see if that works...
Wonder what regressions there are that keep them from using this new engine for all books.
Edit -- indeed it does support popup footnotes! at least in very basic form.
MathML? This sounds very good! Is the Kobo the only reader EPUB3 compliant?
