Another alternative that neatly solves the problem is Custom JavaScript for websites. You just need to install the extension, which takes around 2 seconds, and then you can immediately start typing your custom JavaScript for the specified website.

What you're looking for is Greasemonkey. But wait, Greasemonkey is for Firefox only, right? Turns out, you can install Greasemonkey user-scripts as native Chrome add-ons. Just go to userscripts.org and hit the Install button on one of them, and Chrome will automatically convert it into a native add-on. Then, write your own and install it using Chrome.

Note: This only works in Chrome 4.0.
