Rated 5 out of 5 stars

New version seems a bit broken. Settings won't save. Can't get the button on the menu bar to go away either by the settings or by dragging it out. Context menu won't go away either. Not going to leave a 1 star review, since the add-on is helpful, just thought I should let others know.

This review is for a previous version of the add-on (2.1.4.1-signed). 

Sorry for the troubles! Please try the latest update which has resolved these issues:
