Please consider adding a standard HTML5 viewer template that does not rely on things like Font-Awesome which is neither standard, nor adheres to any sort of disability compliancy (note: Font-Awesome Icons can not be read by screen readers, for the visually impaired). A better option would be to use Scalar Vector Graphics for the icons. It makes little sense to offer a single, non-standard, HTML5 template, out of the box... which forces the end developers to standardize it before it can even be used.
