Doesn't properly render a local file that I tested. Additionally, whether the viewport option captures the entire page or merely the visible portion isn't evident.

Doesn't work. Throws some error. Waste of time. Move along.

the text in nodes dissappear

I liked the add-on, but valued it 4 stars because it captures only the visible part of a page. If you mend it to take a shot of the whole page including areas which can be reached by scrolling, then I make it 5 stars.
