Superb add-on that lets you control your default columns for new folders, reset folders to your chosen viewing configuration, brings back the much needed Cc column to the Inbox and Sent windows (if you want them), and even lets you add a Bcc column. Love the ease of use and the control it finally gives me over my TB workspace. Can't recommend highly enough.
