People really need to give Twicca a try.
Black background, color labels, twitlonger, and all other features built right in.
Dang, I thought I was in the minority with Touiteur! Seems like I don't really hear it mentioned that much. I use the Pro version, and wouldn't even consider a different Twitter client. Touiteur has everything I need....it is an awesome app! Kudos again to LevelUp Studios!
