This is an excellent tool.. I just tried it with the Wikipedia page on New Zealand , it presents the content really well. Very nice.
One thing I did notice though, the "ā" characters (as in Māori) were stripped out.
Would it be possible to have a find/replace when in Design mode? All the headings came across with the word [Edit] in front, and being able to, ahem, edit such text out would be handy.
