I'm using the default awesome theme. One thing I really like is how notifications are handled for pidgin - when a new message comes in the tag label (in the upper left of the screen, on the top bar) turns red.
Is there a way I could make Icedove have the same kind of notifications? I would especially like the tag label to turn red when a new unread message arrives in the inbox. Right now I set my Icedove preferences to "show an alert", but this only generates a notification box in the lower right of the screen.
Update: Installing the "New Mail Attention" add-on for Thunderbird adds the red color notifications!
