More tree variety?

I'm sure it's been suggested, but I would love to see a variety of tree with pale blue wood and pale blue leaves, and a wisteria tree with soft lavender wood as well.  (or give us the option to soften the color of the wood tones?)  Maybe have red maples and yellow birches scattered in among some of the woods and forests as well?  Heck, I know it is a long shot, but I am more than excited to throw in my hat for an inkcap mushroom too.

(and please please please bring in mooshrooms - they have been my favorite mob since I first saw them, and can you imagine mooshrooms in a rainbow of colors? ADORABLE)
