Rated 5 out of 5 stars

Problem solved. As someone else pointed out, this extension does not work with Tiny Menu for some reason. I normally use Compact Menu anyway, so I uninstalled Tiny and installed Compact instead, and this extension now works fine.

This review is for a previous version of the add-on (2.8).  This user has a previous review of this add-on.

Now works with Tiny Menu

Version 2.8 is compatible with Tiny Menu.
