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.

Christopher, PLEEEZ update Columns Wizard! And tell us how to contribute $$ to your efforts - I would be glad to!!

This review is for a previous version of the add-on (6.1.2). 

Sad -
I am on it! I am working on the UI right now for both 68/78
completely new and pure HTML. Check the repository issues as I will be looking for beta testers.
I am also adding the donate button/50% to go to the ALS Association.
Hopefully you can help test/recoup users!
Cheers
Christopher

I always wanted to see a 'Cc' column in my Inbox and Sent tab and now I have it! Thank you Mic! I prefer to view all messages in their own window (not tab) and thus have only one tab open in TB at any one time. This add-on, together with Axel Grude's QuickFolders add-on are the best things ever to happen for Thunderbird, and make the program truly usable.

Install the Columns Wizard from the 'gear' icon in your Add-ons page--'Install add-on from file'. Then restart TB and, in your extensions page find ColumnsWizard 3.0 and click on the options button. Go to the Custom Columns tab and check the box for 'Cc'. Now you can pick the 'Cc' column as an option in your column picker when you right-click on the column headers in any folder.

This review is for a previous version of the add-on (3.0).
