Highlight and Share 2.3.0 has been released, along with some custom goodies such as theme selection and the ability to override Font Awesome classes (useful for FontAwesome 5).
Previously you had to add your own CSS in the customizer to customize the output. Highlight and Share now have themes!
Ability to Override FontAwesome Classes
With Highlight and Share 2.3.0, you have the ability to change class names for the FontAwesome icons, especially if you are using FontAwesome 5.0 and discover the icons are no longer working.
