I am impressed with markdown. It is easy to work with. And you use pandoc you can export md to different format.
The markdown editors that I love are:
- Rmarkdown : http://rmarkdown.rstudio.com/
- atom.io : https://atom.io/
- typosa : https://typora.io/
I love Rmarkdown the most. It can handle latex and use pandoc. If you want to know the power of Rmarkdown against other markdown editors, head here https://bookdown.org/yihui/blogdown/output-format.html
