Rated 5 out of 5 stars

A really useful addition, but the author should check how it works with different sorting methods. For example, when you use email grouping, the icons become completely disorganized. I'd be happy to give a higher rating once this problem was solved.

Edit. Now works perfectly. With great pleasure I give 5 stars.

This review is for a previous version of the add-on (1.2.2). 

Thanks for your feedback, this issue has been fixed in the latest version (2.1.0) !
