Window Resizer

I would imagine sizer could be a handy item for web development. I haven't used it so I don't know how well it works. I'll have to point it out to our developers. One of them simply created a wallpaper for his desktop that had different colored blocks representing the different resolutions basically cascading over one another that he could pull the browser up to and resize quickly to get an idea of how something was going to look at that resolution.
