Click to copy
I know it does the javascript prompt now with the class pre-selected. But would it be possible to make it automatically copy to the clipboard?

And possibly going one step further, giving users the option of which format they would like the snippet in (for example, either `fa fa-check` or `<i class="fa fa-check"></i>`). Kind of like [flatuicolors.com](http://flatuicolors.com/).
