Teak Trees and Weeping Willows

Minecraft has so many cool biomes and plants but only 11 trees including the Mangrove tree and Nether trees. So I came up with the idea to add Teak Trees and Weeping Willows. So Teak Trees would be quite common and found in most forest biomes and would have a thin trunk to represent the trees in real life. WeepingWillows can be found in Swamps and sometimes in the oak forest by lakes. Weeping Willows can have The new fireflies or lightning bugs spawn inside the leaves and fly around which would be so magical
