If you're like me, you're always doing a fuckton at once. Sometimes, even ii-distractmore isn't enough to tell you that someone's talking to you, simply because you haven't loaded any II pages in a little while.

This script quietly auto-reloads a page in a hidden iframe, and if you have a new Distraction? Boom! A little notification appears on your Desktop telling you so.

WARNING: This script will make you appear online just by having a tab open, even if you aren't actually there loading any pages. This can be confusing for others, especially if you fall asleep in the middle of Story. Like that'd ever happen… *hides*

IMPORTANT: This script ONLY works in Chrome and other Webkit-based browsers. I will try to update for Firefox support in the near future.

TODO:

Add a time limit. Make it so that after 30 minutes of not loading a page, the script stops making you appear online. It's not perfect, since you will appear online for a further half-hour after that, but it'll help!
Make it work in Firefox.
