Really useful Rated 5 out of 5 stars

Addon is really useful, this feature should be built in Thunderbird.
Also support is really quick - definitely 5 star

This review is for a previous version of the add-on (3.14.1). 

thanks for contacting me

with your help I was able to fix this Ubuntu issue very quickly:
