Nice! Just this morning I was looking for a solution, because I'm spending way to much time (2-4 hours per post!) with Markdown. I'm a long-time web designer, so Markdown is a pretty simple language for me, but I imagine it's exhausting to other Steemians. You know what I really want: A place where I can draft Steemit posts and save them until they're ready for publishing. Happy to know about hackmd.io.
