You need to look at the GMail Utilities page over at Aimless Words, even if you don’t have a Gmail Account yet (let me know if you know me and would like one, I’ve got a few still).

Gmail is still only a few months old and the online gift/DIY community has already made a ton of improvements to the service via bookmarklets, scripts, web service hacks and the like. While Google may not like all of these “enhancements”, the power of many bright bulbs working on small improvements like this is wonderful to see. (via urlgreyhot)
