A Must-Have Rated 5 out of 5 stars

I run a couple of business, which means that I have to read and keep track of a lot of emails. After finally giving up on the hope of Eudora OSE upgrades, I found myself *far* from in love with T-Bird 17. OSE itself was a departure from Qualcomm's great product that I used for years (until Win7), earlier TB's were a little more, and v17 moved even farther away from what I need, with its folder behavior. That is, until I came across QuickFolders. Now, I can keep the 10 or so folders that I use every day at the top, and run the program like I used to use Eudora 5. It's actually better than Eudora OSE -- assuming it was suddenly bug-free -- because it doesn't create multiple tabs when accessing folders that were already open. It makes Thunderbird useful again.

This review is for a previous version of the add-on (3.11).
