Philosophy
VS Code and Obsidian are powerful because they do everything. Plugins for days. Features for every use case.
markjason is powerful because it stays focused on one file at a time. It gives Markdown, JSON and env files dedicated views, while opening other valid UTF-8 text and source files without pretending to be an IDE.
Different tools for different jobs. Use all three.
