Timber Falls

In short, the Timber Falls addon can be described as a fancier version of Treecapitator. What makes it so fancy is that it features an actual tree-falling animation, as if gravity existed in Minecraft. It also shows chunks of the trunk getting cut out by the axe during the process. I tested this out, and if you happen to stand in the way of a falling tree, it will actually damage you!
