Rated 4 out of 5 stars

Nice work. I thought there was a bug as my selection kept jumping back, until I realised it was because of auto-refresh - it should be off by default.

This review is for a previous version of the add-on (1.3). 

As the matter of fact, this has been changed in already submitted v1.5
It should be available in auto update in a few days or so.
