Feature Idea - Tree Generator

Ok so basically my request is a tree generator. It would work similar to the ore generator. You could input a wood color and leaves color choose a base wood type to base it off of and it would automatically create a tree w/ wood and leaves along with planks, saplings and all of the other things that exist for every wood type (fences, doors, etc.) As for creating the sapling idk how automatic the texture could be so you would just have to make the custom texture for it before generating
 

Also this is related but not fully- for biome gen please improve the trees that can be auto-made. They barely vary at all- maybe just make it so some of the corner leaves can be missing or something because atm they look very blocky.
