Feature:
Right now the falling leaves this mod offers, while good, are really laggy, especially in densely populated forest regions. The big reason I see this being the case is that every leaf block has the chance to spawn falling leaf particles. This is an immediate issue when there are lots of leaf blocks around. My suggestion to help fix this is to add a check to see if the block beneath the leaf block is air. If it is then the particles can spawn, if not then nothing will happen. This will drastically help with the amount of particle spawning blocks without compromising the current look that the mod offers with its falling leaves.

I would also like to suggest adding a blacklist, that way certain leaf blocks could be prevented from making particles or spawning leaf piles(doesn't make a lot of sense for palm leaves, at least not in the same way as the others).

Also adding an option to list what leaves are considered coniferous. It's weird to see BoP redwood leaves spawning regular leaf particles even though they are coniferous.

EDIT: Just saw the blacklist for leaf piles. So I guess all that's need is the particle blacklist, though adding one to the pile blacklist I feel should also just disable to particles for them as well.
