Rated 4 out of 5 stars

very cool but at this time there are a lot of bugs I think because there always dissapear sub menus if I add some. So it is not tthat easy to figure out what works and what not. But I still use it and wait for the updates.

This review is for a previous version of the add-on (5.0.1.1-signed).
