Organize your Inbox with a new gmail feature. Now you can hide labels that have no new messages in them! If you have many labels and get lots of email you may find this new feature paticularly useful.
To turn this new feature on just login to Gmail then click Settings > Labs > Hide Read Labels. Now you may have to get used to using your inbox differently, because each label that has no unread messages in it is only available via the “More” link under your labels, or through searches.
