Feature Request: Associate .markdown file extension

[ScriptingPro]

Currently, UNotes only recognizes markdown files in its directory tree that have the .md file extension. Visual Studio Code also recognizes the .markdown file extension, but in order to see it in UNotes, user has to rename the file to .md and refresh the Unotes working tree.

(btw - LOVE this extension!)

Thanks for the feedback. I'll look into making this possible.
