Rated 3 out of 5 stars

It has a lot of potential, especially since Lighting is so poor as a synched calendar. Sadly, I installed it today, and like many others find that 'Tasks' appear in their window but are visible for only a second or so, then they disappear leaving a blank window that cannot be closed. This is a pain, not only can I not see my tasks, but the rest of the calendar is made small by the blank task window. Shame., I hope it improves because TB needs a good synched calendar.

On the positive side, the Google calendar appears exactly like it does in the GUI interface, and changes made in your calendar in both the tab and the web GUI appear in the other calendar within a few seconds. Creating new events, deleting events and editing existing everts can be made in either calendar.
Once the task window problem is resolved it will be a really good addon.

This review is for a previous version of the add-on (1.4).
