Badly missing this add-on in the current version of Thunderbird as a way of managing my outstanding emails. Can we crowd-fund a working version or can I add my voice to the request that it goes into the Thunderbird product?
This review is for a previous version of the add-on (2.1.1).The add-on is now compatible with TB68 as well. It just took a little longer.
