Rated 3 out of 5 stars

Fantastic Idea! Just need to get the kinks worked out.
As for just making changes to your own Google calendars it appears to work well. However from time to time it "forgets" passwords. On the other hand when using it to view and or make changes to another persons non public Google calendars, even thou you have permissions to view and or change, it seems to "forget" the login and passwords every 30 minutes. Sometimes reprompting you over and over and over again within seconds of typing the password and using the remember passwords feature. Eventually you can make changes/add events to another's calendar for which you have permissions. But the password prompts seem to be never ending.

There is a sync system for Outlook that seems to remedy this issue. However for those of us who hate using "Out Broke" I would much rather get this terrific Thunderbird add-on up to par.

Without an SMS option it looses substantial power to be used as a valid com tool.

Overall this add-on has the potential to be a fantastic Google powered Lighting enhancer. Look forward to new releases soon.

This review is for a previous version of the add-on (0.4).
