Hi, is there a way to use custom icons in the icon box rather than the stock icons offered?
No, right now this is not possible. We plan to add an “icon font uploader” to Enfold which allows the user to upload a generated icon font pack from: http://fontello.com/ and this will help you to use all icons from fontello.com (you’re not limited to the Entypo font family but you can also select icons from “Font Awesome”, etc.). However we’ve no ETA for this feature update yet.
