Doesn't work.. Chrome on mac. Which browser did you actually tested it on? :P
It doesn't look like a good idea to show it to the public before testing it on a few of the most popular browsers... It isn't so hard to do..
That said, the bar to creating plugins these days is much higher. It needs to be testable, and I'd implore the author to add unit tests.
Aside from that, it's quite a bit of page weight for this lil feature. I really would like to not have to add jQuery-ui and store.js to get it to work.
