Structure feature needs some fixing.

The new structure customisation menu is very cool, indeed, but it lacks many things that were already working well. There are no conditions, i can't make structures generate on certain circumstances. Knowing this, i could make a Feature element and put "generate structure" there, but it would be lacking all the other options that the Structure element now has. Please consider adding terrain projection and adaptation to the Structure procedure in the Feature element. Much needed.

Oh yeah structures also won't generate in the nether.
