I like this extension, because Rated 5 out of 5 stars
"ColumnsWizard" can display notes in the header of messages directly in a separate column at the threadpane.
In cooperation with the addons "TB Header Tools Extension" and "Mnenhy" its now possible to add notes at the header of messages and show it. Thank you for your helpful work!
Superb add-on: simple and useful! Rated 5 out of 5 stars
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.
Excellent Addon Rated 5 out of 5 stars
Another good example for an Addon that adds just the right amount of "missing feature" to my beloved Thunderbird.
It works also very well in search results and removes one more unnecessary step from an operation that I do frequently. Thanks for adding the account column as well. I can see that this is going to be even more useful in the future as you have added custom fields so it looks it should be easy enough to add more useful information here in the future.
keep up the awesome work!
