I also have a personalized extension I use for several sites and general browsing. For viewing news.ycombinator.com on my larger monitor, I have it add 25% left and right margins. I also have it enlarge the article titles regardless of screen size so I don't have to zoom every time. If you already know JavaScript, then it's really convenient and easy to pick up.
