The sync tab is empty Rated 4 out of 5 stars

The version 2.1 have some bugs. Sometimes, When you modify some options and click confirm, it dosn't work.
When I downgrade to 2.02, it works well.

This review is for a previous version of the add-on (2.1). 

Hi there - sorry for the troubles. Can you send me a note at tommut@gmail.com with which options are not working you you modify them and click Confirm? We'll take a look right away.
Thanks, Tom.
