EDIT: I'm a fool. This is mostly working, I just didn't enable permissions.

Further edit: Apples only drop if global chance is enabled. If that is false, it doesn't work.

EDIT: See above post

Ah, thanks I'll submit an update to address this today

I've updated the documentation as well about the permission being required in order for it to affect the players

Okie so how it works is if the global default chance is off or on it adds it to the total chance of something dropping.

So by default, I provide some pre-added options like JackHammer, axe.salvaged, rock 

as well as items/clothes that people can wear to add a chance % of stuff dropping 

Essentially if a player has none of these when farming a tree. There chance % (with global default off ) is going to be 0%. Which means they get nothing. 

All of these are changeable inside the config.
