exactly!
manual draw instead of a generator
Personally, I'm interested in procedural generation, not editors. Also there are too many editing tools (Campaign Cartographer, Wonderdraft, Inkarnate etc.) that together cover every possible cartography need - I don't see what my tool could offer that others don't. However I consider adding a "land painter" to Perilous Shores to allow marking which parts of the map should be land and water and then filling it with details automatically.
