De plugin voor de hardcore gmail gebruiker is toch wel Better Gmail.
Deze plugin maakt het werken in gmail zoveel makkelijker.

Google updated Gmail, and now we’re following up with Better Gmail 2, a Firefox extension that adds features to the new Gmail interface. Like its predecessor, Better Gmail 2 is a compilation of Greasemonkey user scripts that add features to Gmail, but Better Gmail 2 works with Gmail’s overhauled interface. We’ll maintain the original Better Gmail extension separately from Better Gmail 2, for users still rocking the older version. However, if you’ve got the snappier Gmail interface enabled and you’re ready for some tweaks courtesy of scripters far and wide, hit the jump for the Better Gmail 2 Firefox extension download.
