Let’s find out whether the Fast Leaf Decay Mod 1.14.4/1.12.2 has any similarity to the Quick Leaf Decay Mod.
This mod is created to increase the speed of the leaf decay after the time all the trees in the forest are chopped down by the players. By default, it just costs you 5 seconds to make all the leaves fall down in front of your eyes.
It is so much quicker and more convenient for all the players to break even the whole forest in just a short time. The leaves will not be despawned in the situations that the leaves of this tree touch the leaves from another one. It is the default in some trees of the Minecraft game such as Minefactory Reloaded, natura and IndustrialCraft2.
In general, though the name is quite similar to each other and they all apply on the leaves of trees, it seems to have nothing to do with each other.
Since this Fast Leaf Decay Mod 1.14.4/1.12.2 gives you more power to control all the trees and leaves in the forest, you should not skip this by downloading the Minecraft Forge. It is very soon that you can create a lot of useful items in the Vanilla world.
