I have only used this to add FontAwesome icons, but with the latest release candidate populating subforum drop-down menus with the correct icons, this addon now does everything I need it to. Great work!
This is one of the smoothest working add-ons I've used in a while. Very good and very helpful. Finally an app for sub-node icon change! And it's free too! Dev is very responsive and on the ball. Thank you again.
