Markdown editor, the BEST or NOTHING!
It's ok. But UI need more customization. You can use flat theme for bootstrap.
This extension can only be opened as a pop-up window. Incredibly annoying.
The lack of side-by-side view isn't convenient, and the absence of advanced features like flowcharts / syntax highlighting (for... bash, perl, asp, php, C/C++, sql etc.) means it's never going to rank higher than "Okay" for me. Added to which, the window chrome seems _very_ odd. I can't imagine any OS being successful with such a crammed UI as it's default. Still, at least it accesses local files easily, can operate off-line and has it's own App window, rather than being a tab in the browser. :)
