Some of our users use rules to move new mail to specific folders in their mailboxes. Unfortunately, when you have multiple level of subfolders, you have to browser all subfolders to check if there is a new mail in one of them.
Why not add the unread count at the top level of each subfolder tree, you'll know immediatly if there is a new mail somewhere in it. Otherwise Traveler is unusable for these users.
