Been working with Joomla for over five years. But could never find a simple way insert HTML code from disk, into an article. This does the trick.
Maybe I'm missing something. If there are other extensions that do this exact same thing, I'd like to know.
Kudos to the developer for such a simple solution.
From what I've seen, the author looks at software from a "user-friendly" perspective, and works hard to accomplish both functionality and eash of use.
