Rated 4 out of 5 stars

With the help of this add on I keep my group of calendars, all of them sub-calendars to a google calendar account, in sync and it just works. sync happens fast and is very reliable.
There is just one &lt;b&gt;but&lt;/b&gt; to this: tasks support is missing. Lightning doesn't accept imported google calendars to store tasks in and google tasks is not supported. I have no idea why a prior review reports that tasks are synced as there is nothing like it in the add-on. In fact, the term 'task' appears just once within the scripts, in a function "getProperty" with <br>case "capabilities.tasks.supported":<br> return false;<br>And since there really seems to be no viable alternative to sync tasks between lightning and, say, an android phone short of installing some collaboration server this missing feature does hurt me. So I spare the fifth star for the day when the provider adds tasks api support

This review is for a previous version of the add-on (0.9).
