Options Problem Rated 5 out of 5 stars

Finally, a resurrection of a great add-on. Thanks!

Strange thing is I don't see third option in Options window: "Labels sub-menus like", just the above 2 options are present? Is it a feature not yet implemented or a bug?

This review is for a previous version of the add-on (1.1). 

Make sure you are using Version 1.1:
