Rated 3 out of 5 stars

The new version basically works with TB 102, but Oauth setup with Gmail is very complex for regular users.
It is also a pity it does not sync contacts photos as it once did!

This review is for a previous version of the add-on (0.4.1). 

Thanks for Your review.

However - as stated in the homepage, in the README, on the GitHub website - I am not the one to be blamed for the complexity of the Oauth setup procedure: this is unfortunately how things must work, it's simply not my fault, and there is absolutely nothing I can do about. Please blame Google, not me...

As per the contact photos, Google-4-TbSync never supported them. I think You're probably confusing my add-on with another (gContactSync maybe?).
This feature is in my TODO-list however, so it will slip into production sooner or later...

Thanks,
MZ
