I love this plugin. Such a convenience to be able to load stories directly into calibre!
My only problem with it is that I seem to be getting some visible code on italics, elipses or dashes, and sometimes at the end of sentences. For example, on this story on AO3: http://archiveofourown.org/works/338120/chapters/547213
Thank you so much for this wonderful plugin! I particularly like how it will grab an update on the latest chapter of a story without having to re-enter the story url. Brilliant.
