Feature Request: A sidebar showing all the md files in the current directory

[justeepin]

I'd love to see an option to show a sidebar to the left of the syntax pane, that shows all .md files in a specific directory (option to select a 'home' directory). Then an option to search all the .md files in that directory. Kind of like how Joplin does it, but you're app is less resource intensive.

Then it'd be good to use as a journal, job log, etc.
