By default, each FontAwesome icon is available with as a specific unicode character when using the icon font. The Felgo IconType only allows quick-access to these characters by hiding the actual unicode strings behind the properties of IconType.
The latest Felgo update uses FontAwesome 4.7.0 as icon font – but we did not yet add all new icons as additional properties for IconType.
The icons are still available, you can have a look at the FontAwesome icons online to see the unicode characters, for example television is available with the character f26c.
Within QML, you can use unicode characters in strings with the \u command, for example:
icon: "\uf26c" // unicde f26c - shows television icon when icon font is used
