By popular request, I've added a quick tree felling plugin. You'll no longer need to spend a half-hour taking down those huge trees!
To enable this feature, type in /maon. Hit any bottom log of a tree, and the whole thing will come crashing down! To disable this, type in /maon again. Be careful to disable this command if working close to homes and such, accidental damage isn't covered by the warranty!
Here's a screenshot of what you can do in a few seconds, courtesy of ADeadlyFish.
