* Now when you click on the back/forward buttons in the popup, the popup text
  shows up instantly instead of fading in. (Improvement)
* The text fades out now as well, assuming you don't interrupt it. (Dubious,
  but easy to remove thanks to...)
* Code cleanups, hopefully everything that's happening is easier to understand.
