Rated 5 out of 5 stars

This add-on is one of the best things about Thunderbird. I've never used the categories feature, but decided I'd give it a try today. But when I try to add a new category, it just won't take. Everything else works perfectly. Categories would make this add-on even better, so I hope the next update will have that ironed out?

thanks for the review! I use QF categories all the time - best thing if you can get in touch via the "support" tab on the QuickFolders Options screen - there is a link to send me a direct email on the bottom!
