Like, there's a million text editors, and thousands supporting markdown, but I've never heard of one with support for the markup language used by @mediawiki, the biggest wiki software in the world. Isn't that a bit strange?
Also, is this markup language really named "wiki markup"? If so, then why isn't it even on Wikipedias own list of markup languages? They use it, but don't list it!? O.o https://en.wikipedia.org/wiki/Comparison_of_document_markup_languages
