It would be nice if the web site would tell us what license governed the use of this software. It sounds like a useful program, but there would be no point for me to spend time installing it if it were not free for commercial use (and free of adware, etc.).
Hey I'm the creator of MarkdownPad, it is free for commercial use and has no adware. I'll add that information to the site, thanks for bringing it to my attention!
