Is there a demo? I know you liken it to Github's, still it would be nice to see the real thing. I'm currently implementing autocomplete through jQueryUI and this is something I'm interested in.
Yes, there is a demo. It's in the header of the GitHub repository page.
I guess I should include a link the `README.md` file.
Yeah I missed that, I always assume it's in the readme. Feels great to use. For some reason hitting tab is making it focus on the address bar, not sure if it's because of the code or something to do with the demo page. One other suggestion is to allow space to autocomplete like enter does, since usernames are never spaced.
