Good 4 Web Designers Rated 4 out of 5 stars
I do a bit of web development, and it's useful for checking to see how your page would look within smaller resolutions (as most people don't have a 23-inch flatscreen!)
One idea may be to have buttons that allow you to click to resize your browser to a certain size (say 1024x768).
