Lifehacker Code: Better Gmail for Google Chrome
http://lifehacker.com/5180011/better-gmail-for-google-chrome

Windows only: Better Gmail for Google Chrome is a compilation of user scripts designed to enhance your Gmail experience—and to make it easy, we've tested and bundled them together in one easy download. Better Gmail for Chrome is inspired by the well-known and grown-up Better Gmail extension for Firefox. Like the original, we've packaged up a bunch of scripts that we've either tested successfully or modified to make them work correctly—since Chrome doesn't have full Greasemonkey support we had to make a few modifications to some of them.
