I've been looking for something like this lately, it really fills a need for me!
But you really REALLY need to modify your icon. There are a million bookmarked shaped icons in this world, and for some reason no-one ever incorporates a mark with the bookmark icon so that it can be differentiated. So now on chrome I have 2 bookmark icons that look identical (the other is for 'read it later'), and two other ones that relate to bookmarks but are stars. Great.
