New script for you guys!
This is just a little one I had waiting in the wings while I'm sorting out some cross-browser compatibility stuff with Hush. It's nothing special as far as names go, I call it the Quoted Text Monitor. I recall that someone had made one for the old NG at one point in time, so I revived it.
Pretty straightforward, install, and whenever you post, you'll get this percentage meter that shows how much of your post is quoted content. I was considering making it lock the Post button if you're over, but I don't know the exact percentage NG cuts off at. I've estimated it at 83%, so going over that will cause the meter to turn red.
Compatibility: Chrome, Firefox 10.0.2+
