Lush Caves Feedback Sanpshot21w10a

I really love the lush caves so far, I think they're absolutely excellent!
I think it's great that you guys put clay down there, it's definitely going to fix the problem of it being too hard to find. I think there's just too much of it now. In lush caves I would suggest you have the following materials also generate:
-Calcite: Calcite looks so cool, and it would be a shame if it ran into the same problem as clay where it was so rare it was unusable. Making it generate in lush caves would be awesome.
-Limestone: Limestone fits the look and feel of the lush caves, and it would really add a lot to the caves if it were added in. 
In general I think more moss should also generate.
Other than that the lush caves are spectacular and I really like them!
