Hey,
I was playing around with your mod and really love the concept and the looks of it (especially with the new underground rivers, they look amazing).
One thing was bugging me though: The rivers looked very out of place going through a Desert. So I wanted to turn them off, but didn't find the option in the config file. (In fact, there wasn't even a config file present.)
Is it possible to add a config file, where we can white/blacklist biomes to spawn rivers, and if so, are you planing on doing so?

I would highly appreciate this, too. I'm playing with RTG and Biomes O' Plenty, and the rivers simply don't fit in some of the biomes like Outback or Wasteland.
