@tobbecokta would you be able to try a development version in your environment to see if it resolves your problem?
I have a major update to the plugin, planned for release soon, and I’ve had this issue in mind while working on it. I hope it resolves your problem. It would be helpful to get some early feedback, if possible.
Because it’s a major update, though, this new version of the plugin stores settings and things differently in the database and handles conflict detection and resolution different as well. So if you were to give this a try, you should imagine deactivating and uninstalling the current Font Awesome plugin, taking it back to a clean slate, then starting from scratch by installing and configuring this new one. And then, when this one is released, doing it all again to make sure you’re up and running with the new one. It would be some extra effort for sure, and may not be a good idea to try on a production site. But if you’re willing, then it might be beneficial to us both.
