Damocles,
Thank you very much for putting so much work and care into this amazing map generator. I absolutely love the degree of control it gives me over the map. I really enjoy the added realism of having certain POI separated from cities and towns in a more logical manner. So again I can't thank you enough for creating such a fantastic tool. It's obvious to tell you've put in a lot of time to create Nitrogen and you deserve a great many kudos for it.
Another reason I'm writing is that I had a thought for a possible enhancement: Currently a user selects biomes from a menu, but I would really enjoy being able to select biomes using checkboxes. For example I want to try a map that is wasteland + burned or perhaps wasteland + burned + desert. I'm hoping that implementing this enhancement wouldn't be too difficult. Another idea, which I believe would be more difficult, takes this a step further by allowing the user to select not only which biome(s) they want but also how much of the map is covered by that biome (perhaps by using slider controls similar to the way the user selects the landscape).
I completely understand that you're busy and that you're working on Nitrogen as time permits. I hope you will consider my suggestions, but even if you don't find the time to implement them Nitrogen is still a magnificent program. Honestly it deserves to be integrated into the game, it's just that good.
Thanks for your time!
