Rated 5 out of 5 stars

Works perfect !
Thanks for the hardwork and now its easy to have a quick overview of email stats.

Just one request though, could you display the day of the week also (praticularly helpful in custom view) to check for trends.

And down the line if there can be w-o-w, m-o-m,y-o-y comparison it will be even greater

This review is for a previous version of the add-on (1.4.4). 

Thanks - credit goes to Micz, the original author!
I can look into the day of the week tweak as I work on the Thunderbird 68 update.

curiosity question: what language do you use? Are there any missing locales you would like to see?
