I often listen to CBC Radio 3 at work. Recently they updated their website; while it’s mostly a change for the better (yay, the player doesn’t stop updating!) there were a couple of things bugging me about it. With the old design, you always had access to the player and the main navigation, but now they stay at the top of the page. Not helpful when you’re scrolling through comments and whatnot.
So I wrote a Greasemonkey script that keeps the player and the left navigation bar in place. It also clears out the CBC header at the top, as well as the CBC Radio header that sits below that, for a cleaner page.
