Hiya - I created a (free) plugin to scratch my own itch - it’s a button that allows you to use Font Awesome icons and Bootstrap buttons. You can either use the standard Bootstrap styles by setting the type or override these with your own custom styles.
Any enhancements/bugs please just let me know and I’ll get it sorted. Can be seen in action: https://rymawby-plugin-testing.bubbleapps.io/
