Adds a small panel that shows you how much time you've wasted on the @match websites, and shows you what you could have done in that time instead.
Wasted is a simple script that adds a panel that shows you how much time you've wasted on a website. It also adds a button where you can click it and see what you could have done instead during that time.
This has been tested mainly on reddit.com, but should work for any site in @match. Please feel free to @match any more sites.
