Rated 4 out of 5 stars

This add-on is great, I have been waiting for something like this for a long time. However, it seems that Thunderbird doesn't save a local copy of the calendar or calendars every time it synchronizes, and so, if you are not connected to the Internet, this app is useless. Doesn't make much sense to assume that you are always going to be connected...
Anyway, thanks a whole lot for your work...

This review is for a previous version of the add-on (0.1.1).
