Great job! Rated 4 out of 5 stars
I like the panel at the bottom of the screen, however, only the half of it is used and the rest is wasted, you guys could add something useful here for the next release.
I was having problems with reminders, for some reason I wasn't receiving them even when I reinstalled the add-on. but with this release it was fixed.
After restarting Thunderbird, I was so worried because my calendar was empty. When I added a new one, I got all my events back so, you should fix this too to avoid suicides :-) .
Keep up the good work!
