I can see that the author shares the best distraction-free writing environment he realized by tweaking plugins and configuration, which works for himself/herself. Which is awesome.

However, it should be noted that Vim already is a distraction-free writing environment, and Markdown is quite simple enough. A vanilla Vim with Markdown highlighting is actually enough. In fact, as long as being "distraction-free" is concerned, just VI should be enough.

Althought I am all for tweaking, I always keep in mind that sometimes I am better off tweaking the writing itself, rather than the tools.

I am sharing this because sometimes we tend to get lost in configuration, and we need reminders to get out.
