Enable Markdown Support

I typically use the ScreenSteps Desktop Editor for macOS.   Recently, I've been creating a great deal of documentation in markdown formatting.  I'd like to be able to use markdown formatting rules (similar to the Github rules) to format text, code, code blocks, and tables on-the-fly.   My feature request is two-fold: 

• Accept in-line formatting via MarkDown within the desktop editor. 
• Could we have a preference setting for the Screensteps desktop editor for macOS that could change from the traditional view to a "markdown editor" view (similar to Visual Studios Code and most other markdown editors where the markdown is in one pane and the preview is in the other)?

Thank you!
