Temperature Bands (by CosmicDan)
Strongly recommended for best results.
Temperature Bands changes how climate and temperature gradients are organized, making the temperature map view significantly more informative and visually consistent when exploring world generation.
This addon works perfectly without it, but Temperature Bands greatly enhances the experience.
