Most modern editors are either:

• IDEs/code editors (usually "fat")
• browser tabs (not user-friendly)
• diff/merge tools (over-featured)
• overly complex writing suites (impose a 'way or working')

This app was created specifically for:

• side-by-side plain text file editing
• reviewing unrelated (different folder locations) documents simultaneously
• markdown/text workflows
• lightweight desktop productivity

without requiring a full IDE.
