Suggestion: Restricted gravity depending on block above

[ghost]

I disabled dirt/coarse dirt/modded dirt from being granular because it creates loads of floating trees. Would it be possible to create an option/mechanic that prohibits certain granular blocks from falling unless the block above is either air or another granular block? It wouldn't be perfect, but from my observations it would limit the amount of oddities.

Thanks for your suggestion, I'll take a look into implementing something like this.
