I love the action buttons and the countdown timer. Very useful, though I might suggest optionally pausing the timer when the user mouseovers; that way if they want to take an action things are suspended. On the whole, it's a bit rough around the edges (close button is not always in the right spot on Chrome on Ubuntu; overlaps with the scrollbar, etc.) and I wouldn't use it in production just yet. But it's a great contribution.
