It has recently come to my attention that Flarum only takes font awesome inputs such as fab fa-apple, but when browsing font awesome however, I found that quite often, simply copy and pasting the class name of the icon "as is" will not work. For example, this icon comes with the icon class name fa-brands fa-apple. An inexperienced user will try to put that "as is" in the icon field and be surprised to see that it doesn't work. The trick to making it work is abbreviating "fa-brands" to "fab" automatically, same being the case with other icon names such as fa-solid to fas. There are probably more names that I know of, but making the copy pasted icon class names work straight from font awesome might be a good quality of life improvement for new users
