Traverse outliner

Traverse helps you shape writing, research, projects, and personal knowledge in plain OPML files. Work in a classic outline, a focused Writer view, or left-to-right columns, then add Markdown, Fountain, tasks, filters, and custom attributes as your thinking becomes more structured.

Main features:

• Local-first outlining with portable OPML files
• Three views: Outline, Writer, and Columns
• Markdown and Fountain modes for documents and screenplays
• Tasks, filters, numbering, focus mode, and custom attributes
• Export to OPML, Markdown, Fountain, CSV, or PDF
