And typora is thre for Linux, I tend to use Marktext lately for distraction free writing.
Has a similar feature set to MarkText (tables, diagrams, math, code blocks), with the addition of: typesets to PDF, automatically curls straight quotes, can use inline R statements, offers interpolated variables, has distraction-free ability, document statistics, and you can position/resize/rearrange its tabbed panels to your liking. There's also a command-line interface for use with scripting.
