If you’re using Gmail like I do for most of email/calendar/docs/etc, you should take a look at Lifehacker’s compilation of Greasemonkey scripts for Gmail. If you don’t know what Greasemonkey is, download Firefox and start looking at how to boost your productivity each day with these simple scripts!

Gmail‘s good, but it could be better. We’ve featured several Greasemonkey scripts that enhance Gmail in lots of different ways – like adding saved searches, attachment icons, label colors, keyboard macros, a filter assistant and right-click conversation previews. But not everyone wants to install Greasemonkey and hunt down all those scripts.
