Gmail’s blog announced that 6 labs features have graduated (Search Autocomplete, Go To Label, Forgotten Attachment Detector, YouTube Previews, Custom Label Colors, Vacation Dates), while 5 other features are retired from Gmail Labs (Muzzle, Fixed Width Font, Email Addict, Location in Signature, Random Signature). Google says that “these decisions were made based based mainly on usage,” so that’s the reason why obscure features like Muzzle, a quick way to hide Gmail chat status messages, or Email Addict, which blocked Gmail’s interface for 15 minutes, were removed.

The good news is that 2 labs features will greatly improve Gmail search: “Search Autocomplete” and “Go To Label”. If you have many labels, it’s difficult to find one of your labels, especially if you added the label to the “more” dropdown. “Go To Label” adds a keyboard shortcut that lets you quickly open a label: type “g l” and then type the first letters of the label you want to find. more details can be viewed at google system blog..
