thunderbird

A couple of weeks ago, we announced the release of Thunderbird's "Me Menu" integration in Ubuntu 11.04.

Just now, Mozilla has released an experimental extension, "Unity Launcher Integration" 0.1, that lets Thunderbird integrate with Unity dock/launcher (Natty Narwhal only).

Our lovely Natty Narwhal is growing every day and, even it's just an alpha (2), receives lots of new functionalities almost daily.
One cool, interesting feature is the new Mozilla Thunderbird extension that integrates Thunderbird into the Messaging Menu (currently, available only for Ubuntu 11.04, Natty Narwhal).

So, what is this Mozilla Thunderbird extension good for?
