I don't know how all this works but I'd like to see butterflies added in and being able to use the wings for stained glass windows. With the lighting in the game it'd be awesome to see that inside the house in the early morning hours or evening. 

That's a great idea! However, I'm not sure if that is possible if real-world physics is considered, as butterfly wings rely not on pigments but on the specific ways lights got reflected. It would nevertheless be cool to be able to collect the scales of their wings and color one's armor or buildings.
