I could always use RichWidgets Icon...
The thing is that RichWidgets Icon has not changed much since it was launched. It's currently in 4.1.0/4.2.0 version of the Font Awesome (depending on which version of the platform you are in), and it does not allow you to use any other iconsets.
The rationale behind this little project was to spare others from the same mindless work that is required to upgrade Font Awesome, and to give the possibility to use other icon libraties that I found usefull
Having that in mind:
