Some ideas: boolean whether or not a tornado can pick up waterblocks(and lava) (or maybe completly disable flying water blocks because this is not very realistic...) I think it would be nice if you could also decide whether or not the fallingblocks should be placed boolean whether or not entities should be picked up
EDIT: boolean whether or not blocks should be picked up EDIT: boolean whether or not "real" blocks should be picked up (what I suggest is to create those picked up blocks ONLY and not remove them from landscape)
I'm guessing you are asking if I'm from Brazil, if you take a look under my name it says I'm from Sweden ;)
