Fixed the worst issues...now it is usable but lacking.

This version is much improved from the last one in functionality. The integration of interactive graphics and additional content is quite nice and this is an enjoyable way to read SA. But, I dont understand why you cant pinch and zoom articles or text to a personalized size or why there is no support for instant definitions or searching interesting terms on the web by highlighting. Maybe they are going for a bit of PDF feel.
