I like this addon but I miss one feature (for my workflow). I would like the option to simply copy the URL and no shortening taking place. (I need to paste it to another application. Some sites the short url fail and I suspect it might be an error on behalf of the webmaster but it disturbs my workflow anyway).

Edit: setting shortening service to none does not work since the shortening embedded in the HTML is still used. Many websites I have seen uses an invalid shortened url in their HTML.
