Field notes
The app says its 23 record types range from races and religions to languages, magic, and economics. Its map tools include layers for locations, regions, factions, and events, while manuscript references can point back to character and place records. The roadmap also names future additions, including custom fields and templates; its dates are explicitly described as approximate.
