CloseReview for Set Default Columns by Anatoli
Rated 5 out of 5 stars
I have written a review for the previous version: everything was fine except that there was no possibility to reorder the columns.
The new version fixed that issue, now it's just perfect!
Check my previous review for a way to change columns for *existing* IMAP folders using this add-on.
