Better Gmail 3 provides a quick and easy way to better organize and cleanup your Gmail account when using Google Chrome.
Once you click on Install (small extension window), Better Gmail 3 is ready to go and you are taken directly to the options. As you can see there is quite a bit to work with. Simply go through and select the actions that you like or need and click Save. If you had your Gmail account open in a tab during the install, then you only need to refresh it to see the differences.
