I updated this with a bunch of new functions! Thanks for the replies/suggestions. This is still on my todo list:

• bookmark alert
• stuff floating around mouse
• move messages in the status bar

I made some fixes and jshinted the code! https://gist.github.com/998465

Thanks, I merged the changes back in! :)

doesn't work on chrome, here

Do you think that the 'a.stayOnSite = function ()' is still evil in the age of tabbed windows? Even sites like blogger give users the option of having links to pictures and other sites opened in a new window/tab...

doesn't work...how annoying :D

What is in s, and why do you throw away the text value in copyToClipboard() ?

Opening links in a popup - it would be easier to assign target="_blank" than to create a popup ;)

A "force video autoplay" and a "recurrent pop-in" feature are missing.
