Little plus in Linux Rated 5 out of 5 stars

I complained in a previous comment about a previous version where the plus is hard to click. The latest version of this addon has fixed that, and therefore this addon is perfect.

This review is for a previous version of the add-on (2.0.0). 

The little plus is annoying in linux Rated 3 out of 5 stars

It is hard to click. Customisability is nice, but for an addon that exists to address the grievance of a feature missing from a previous release, I think there should be an option for "Thunderbird 2 behaviour" no more, no less. Thats all I want.

This review is for a previous version of the add-on (1.4.6).
