Rated 3 out of 5 stars

Hello,
nice app, but a major problem during my tests :
if I am offline on thunderbird and I add a task, and if during that time, I add another task directly from thunderbird, he make a merge of the two, and not two separate tasks. ==> we cannot work with two device at the same time if they are not syncing directly...

This review is for a previous version of the add-on (0.5.1).
