It looks to me like you can stick the content into a container or not. From a coding standpoint, it's adding a <div> around the RTE content, presumably. I know coding directly gives you plenty of control. Great! if you like that, more power to you. With my limited available free time, I'd rather be creating content, not formatting it. At least not in code that typos, which I have a lot of, causes messes you have to figure out.
What I am asking for is not a zero sum game. You can get your pretty box, I can get mine and we're both happy 🙂
