Good Addon I might change it to 5 stars if i'll see getting pinged or anything when my primary group shout changes.
Edit1 it does not notify you when there is new shout on group. changing from 4 to 3
Edit2 It Seems That it got fixed or it started working for me, but still i don't know if it will notify me if it does i will make 3rd edit for now i'm chaning from 3 stars to 4.

Really good extension. It would be better if you had the option to revert back to the normal profile layout (now it's just a mess of games your friends are playing, recently played, favorites and random games.)
