Rated 5 out of 5 stars

This is exactly what I was in need for, but I need a button or shortcut that is mouse friendly please, like in right click menu on the tabs bar perhaps.

This review is for a previous version of the add-on (0.1.7.3.1-signed). 

Hmm... there is button for toolbar, just call "Customize…" from toobar context menu.
