I'm attaching the source.
I'm all for OSS but I didn't want to publish it right away as somebody could change the colors, reupload it and get more users. And now that as many as 11 users installed it I am unsurpassable!
There are some unnecessary files which I've removed before uploading the file to Webstore.
If you have any suggestions - please share. I'm most interested in a way to make it faster to get all ranks to display in the table (it takes a lot if there are more than 2 of them).
BTW The extension didn't work for me lately (and for one more user) until I've updated Chrome. So if you have and problems I suggest you do that.
