Rated 4 out of 5 stars
Seriously, adding a new (anonymous) group should be way faster/easier for this to be actually usableThis review is for a previous version of the add-on (0.9.1-signed). This user has a previous review of this add-on.
Quite the contrary, the concept of this extension is that every groups should have a name. If you want anonymous group, then this extension is not for you.
