I, like many others, have numerous links all over my website. Some are in the body, some are in the sidebars, some are in comments. When links go to an external site, I would very much like to have that website's favicon appear to the left of the link. I have seen this in many places. E.g a link to Wikipedia page, should have that wikipedia favicon.
The plugin File Icons appears to do that, but for file types (you link to a PDF, you get a PDF icon). But the question is, how do you do this for general types of links? You could add URLS to the File Icons plugin by hand, but that is a pain, and I have heard of Google's S2 which should find most fav icons automatically.
So my question is; is there a plugin that will auto find any links on a post/page/etc. and insert the URL's fav icon to the left of the text?
