Nice and need help Rated 5 out of 5 stars

This is quite efficient when I use "mail summaries".
But in practice, when I have many mails in the same folder, I have to scroll down to the very bottom to find a blank space to click. Can this be improved? Like clicking on the folder name or somewhere else? Thanks.
P.S. I am using "quick folders" and have folder (also search folders) tabs on the top.

This review is for a previous version of the add-on (1.0.1). 

If the message pane is full you can deselect a selected message by control clicking on it for Win (command clicking on Mac).

I created this add-on for my personal use and decided to share it. It is highly unlikely I will refine it other than to make sure it works with future versions of Thunderbird.
