How to Use Favorite Folders in Mozilla Thunderbird

One of my favorite features in Thunderbird 2.0 is favorite folders.

Instead of being confronted with a daunting list of folders, I can look at just a select few (for me, my 2 primary inboxes).

Right-click on a folder, add it as a Favorite, then use the little switchees to move from All Folders to Unread Folders to Favorite Folders.
