And at first I was impressed by the overlay, especially considering the novel implementation. However, after a little thought and setting that novelty aside, I think that effect is broken.

Worst case scenario, an unsuspecting user activates an overlay button, and while it's loading, starts clicking state-changing buttons around the page just to kill time.
