Rated 4 out of 5 stars

Very nice & easy on the eyes! And little if any BLUE.

One minor issue: When Quick Filter is active, the buttons for Sender, Recipient, Subject and Body do not remain highlighted after being toggled on.

Aside from that FIVE STARS!

This review is for a previous version of the add-on (1.2). 

Thanks for the review and finding the issue with the Quick Filter toolbar! Should be fixed in the next update (v1.3). It will be live as soon as it is approved!
