I have changed this from a bug to an improvement request:
Since Font-Awesome is brought up again, I want to bring up something that happened after our last switch from status icons to Font-Awesome. We got complaints from users who already had modified status icons (by uploading them to the icon directory). When it was explained that it was now possible to modify the look of the icons via CSS, many did not know how to modify CSS to do this, even if only to replace the font character with their previous custom icon image.
It was overlooked when we made that switch and seems to be overlooked in many discussions about implementing Font-Awesome in anything: there is a marked difference in technical expertise:
1. Editing an image in a graphic design program and uploading it in FTP.
vs
2. Modifying CSS background properties and/or unicode entities.
The second requires knowledge of CSS. I am wary to simply switch more icons to Font-Awesome without considering a path for these users or developing some sort of tool to make management of Font-Awesome icons easier. This verges on needing an entire new feature developed, even outside the scope of what's already available via XenForo's Style Property system.
