Rated 3 out of 5 stars

Running Ubuntu 12.04 with Unity. Everything works as advertised except minimizing leaves the Thunderbird app sitting in the launcher. Closing the apps works great thought, TB dissapears but sticks around to give notifications and indicator updates. Very good add-on for those of us that make use of workspaces.

This review is for a previous version of the add-on (0.4.3.1-signed).
