Second, Gmail’s Priority Inbox has been added as a view option. This option is in a drop-down menu in the inbox itself. (There is also is an “Unread” filter in this drop-down.) These priority messages are marked in Sparrow by the familiar yellow indicator that Google uses.
The coolest addition is the multi-touch gestures. You can now pinch two fingers to both open and close messages. Three-finger swipes left and right will now show and hide a message in the panel. And three-finger swipes up and down will navigate through messages. All of these require a trackpad (though two-finger swipe on the Magic Mouse opens the panel), so if you’re using Sparrow on a desktop Mac, you’ll need the Magic Trackpad. Still, very cool.
