CloseReview for Thunderbird Conversations by jacob
Rated 3 out of 5 stars
Adds a useful feature, but during installation it reorganized my folders and changed my layout without asking.
This review is for a previous version of the add-on (3.1.16).The add-on gives you an introduction page where you would have chosen to apply changes. There's a review option on that page where you can decide not to change various items.
Some of that is not as clear as it could be and we'll be improving that soon.
Also both the add-on homepage and the FAQ reference the fact that if you don't like the alternate folder layout, then you can change it back by "View > Folders > All".
