New biomes and improvements to some

It would be a good idea to be able to implement a new biome which is like an entrance to the desert to give more realism to the game because sometimes it seems strange that you find a green area and next to a desert which looks something strange, and it would be good to put a biome where you have to cross it to enter the desert, as you advance in the biome you are closer to the desert, it would start in a light green area and from there it changes little by little. As for improvements to biomes, it would be good to improve the jungle by adding more plants for the ground so that it does not look empty such as different flowers, herbs of different shapes and etc., also the swamps would be good if they had fungi, flowers on the ground but in a different color, so you don't feel empty
