The HN effect: Visited the project 3-4 hours ago, and it had 40 stargazers, now 650. :) I really like it by the way, and I think I'll use it for my next project. How about some events though? Like `introJs.on('5', fn)` would execute `fn` when the fifth hint is shown. It could be used to introduce several views to the user (one page app).
