Very nice job, easy to personalize with own preferences.
Especially useful the possibility to highlight!

Just a small problem, in my experience, that I have overcome with the continuous page view: if you augment the font size or the line spacing, altering the initial number of pages of the book, you cannot view the content at the end of the last page of the chapter, sometimes even large parts of content. If you can solve this problem I think it could be very useful for everyone.

Many thanks for this beautiful extension.
For me a worthy substitute for the new version of epubreader, whose interface I really don't like.
