CloseReview for Extra Folder Columns by PMDonovan
Rated 5 out of 5 stars
Fantastic! I relied on this feature in all versions prior to 3.x.x. I was very frustrated without the information because I have at least 1000 folders and sub-folders. It how I've been browsing my e-mail to find items for years.
Thank you very much.
