I noticed that the [icon] pulls in the class gk-icon to the html. Johns icons work with -flame, -heart, etc.
In the template settings I set all of my header tags to pull in squirrel fonts and link to font-awesome. I am not sure which tag to use in my title to create the fa class that I want. Should johns Icons still work even if the settings have changed to font awesome?
I am trying to use http://fontawesome.io/icon/cogs/
