Thanks for a great generator! I am creating a fantasy world this 30 years. This generator is a great supply for my weak point --- lack of visual informations. I have some requests for the river in this generator.

1. River with unstable width.
2. Two or more rivers.
3. River mouth with delta.

I have some rough sketch of the cities in my world. So my true wish is... pre-definition for coast, river, roads, or wall lines.

I'm working on something like that: https://twitter.com/watawatabou/status/1026594088353705986
