I use a lot of labels with icons all the time, this makes the job way easier to manage.
I think this PR is complete, I tested it works just fine for me.
I hope you also find it usefull, feel free to change anything I may messed up

@torresdistrib Thanks for the icon implementation! Certainly useful.

To merge this, we will need to make sure it is backward compatible and the feature can be disabled.
Additionally, it would be nice to have a dropdown with icons to choose from or something, to make it more user friendly, since most content managers do not known the font awesome css class by heart ;-).

Do you have time to contribute this?

I'm glad you find it useful!

I didn't test for it, but you're correct; it should be backward compatible, and I believe it should be easy enough to do (given my available time and limited skills).

I agree with you; it's a very niche area of knowledge :) Nonetheless, it's easily accessible. My main concern is around the naming of the classes, as they strongly correlate to the FontAwesome version you are running (and whether you have the Pro version or not). Not to mention the variants of the same icon that you can have. I simply can't say that I understand FontAwesome well enough to build an automatic dropdown that accounts for all the versions, etc.

Let me know if that's a deal breaker or if you want me just to check backward compatibility.

All the best
JT
