After playing with [Caret.io](https://caret.io/) for a little while, I think I might have found the cross-platform Markdown editor that I have been looking for. Nice and minimal design and seemingly has all the features that I am looking for. Also it is a lot easier to maintain, than my current Atom.io setup.
@fredmbarros Juu, so far I like this one. There are only a few things that I would like to improve: https://svens.blog/2017/05/28/caret-a-markdown-editor/
