The Mac email app Sparrow is now more social with Facebook profile integration.
Mail contacts will now display a profile picture or Gravatar from Facebook friends.
The other version 1.2 interface improvements include a unified inbox for those with multiple accounts, the ability to create a rich text signature, several User Interface tweaks and, most importantly, the Sparrow dock icon now bounces.
The developers promise that future enhancements are coming in Version 1.3, with label management and a “secret feature” on the way.
