Rated 5 out of 5 stars

It's the best add-on available to sync tasks with Google.
Some suggestions:
1) Add sort by name
2) Adding the task with Enter key in the "New Task" window
3) Canceling the task with Escape key in the "New Task" window
4) Add "Sync Interval", E.g. sync with Google every 5 minutes or every 3 minutes

This review is for a previous version of the add-on (0.5.2).
