I am glad I bought a license for this nice add-on. The default editor Redactor scrambled parts of my code, even when working in HTML source mode. But this Markdown editor lets me write a mixture of Markdown and HTML, and the code stays the same, exactly what I typed. The output looks as it should, too.

So I can recommend this add-on for all those guys who don’t like the WYSIWIG editor Redactor, but also do not want to use HTML blocks.
