Willow trees

Willow trees would be a really nice addition to the game, I think. They would bring new shape to the natural landscape, with their elegant, sweeping branches, and it would further diversify the already wonderful pallet of colours and textures, both in woods and in blocks overall. Furthermore, willow trees filter water through their roots, so they could change the colour of the water within a certain block range of their wood, which would be a really interesting visual mechanic, and would work with either being integrated into a pre-existing biome, or implemented into a new one. I hope you consider this idea, thank you for your time :)!
