Unlike other userscripts, this one integrates perfectly into the page as if it was part of Youtube itself. It's so unobtrusive and uses the space and place that is just perfect for it to be unobtrusive. For sure the best solution to integrate download links for Youtube videos. Absolutely perfect! Thank you

This is a perfect example how user-made Javascripts should work. A simple but effective addition.
Surely one of the best Userscripts!
