Nice addition. Works great.

I noticed the layout looks a little funny on Mac [0].

Also, I ran across a GPL-licensed WYSIWYG HTML the other day that
might be useful to slim down and strip out fluff, then include into
QGIS core for HTML editing widgets like this [1]. Doesn't have to be
WYSIWYG, per se, but nice for users. Built during Qt 4.5 release so
should work for QGIS distribution Qt base, although might benefit from
a reworking with regards to some 4.6-introduced stuff like QWebElement
[2].
