Quote from SilverStorm
Not sure if this what you mean, but there's a script that does that, sort of:http://userscripts.org/scripts/show/61549
(Requires a script handling program like greasemonkey/scriptish/tampermonkey on your browser.)The icon only shoes up after you've clicked on the manga info page before though.
Ohhhh this is pretty awesome. :'D
Thanks for posting!
And whoa, chulian has some other great scripts~! <3
