Add class and no follow to button or link

Hi Jeffery,

I’m enjoying the nice functionality that the plugin adds for Gutenberg. A feature / suggestion is in relation to links and buttons. I like to add a class to the links so they get styled as a button, but that is not possible in Gutenberg. Is this something that you could add? Conversely, buttons allow you to add a class, but don’t have the no follow and open in a new tab options.

Thanks,

David
