Genius idea. I love being able to put social network sites in their place (!) / in to their own box, keep shopping sites separate from everything else - plus this add-on comes with even more cool features... It hands some power back to us users. And while it is very good already in what it does (worthy of 5 stars), how it is used can be improved with a few tweaks - therefore 4 stars. Still, this is an add-on I don't want to be without. Ever again.
