Please update the component - it has been refactored and a 3 option list setting is now in place instead of the previous boolean. Also it now uses the proper plugin outlets and avatars show up in the related/ suggested topics footer. (thanks @awesomerobot) 
At some point in the next few weeks or so we will move it to our org and tag it as official and update topic OP.
edit: updated the OP with theme creator preview link.
