Some semi-random thoughts on terrain generation

[NiLSPACE]

There are still no overhangs in Desert-, Taiga, jungle and forest hills. is that meant to be? also Deserts still need sand
EDIT:
lol i was looking for a forest overhang for days but didn't find one, now i was looking at a extreme hills biome, i turn around and there is a overhang in a forest..
EDIT:
That Chunk generator performance message realy spams the console now
EDIT:
Also mushroom island should have the same generation as extreme hills exept the grass.
