Tree Harvester

mustHoldAxeForTreeHarvest  default true
If enabled, tree harvesting only works when a player is holding an axe in the main hand.

treeHarvestWithoutSneak  default false
If enabled, tree harvesting works when not holding the sneak button. If disabled it's reversed, and only works when sneaking.

automaticallyFindBottomBlock  default true
Whether the mod should attempt to find the actual bottom log of the tree and start there. This means you can break a tree in the middle and it will still completely be felled.

enableFastLeafDecay  default true
If enabled, the leaves around a broken tree will quickly disappear.

enableNetherTrees  default true
If enabled, the warped stem/crimson trees in the nether will also be chopped down quickly.

enableHugeMushrooms  default true
If enabled, giant/huge mushrooms will also be chopped down quickly.

ignorePlayerMadeTrees  default true
If enabled, trees with leaves placed by players won't be destroyed.

replaceSaplingOnTreeHarvest  default true
If enabled, automatically replaces the sapling from the drops when a tree is harvested.

replaceMushroomOnMushroomHarvest  default true
If enabled, automatically replaces the sapling from the drops when a huge mushroom is harvested and 'enableHugeMushrooms' is enabled.

loseDurabilityPerHarvestedLog  default true
If enabled, for every log harvested, the axe held loses durability.

loseDurabilityModifier  default 1.0, min 0.001, max 1.0
Here you can set how much durability chopping down a tree should take from the axe. For example if set to 0.1, this means that every 10 logs take 1 durability.

increaseExhaustionPerHarvestedLog  default true
If enabled, players' exhaustion level increases 0.005 per harvested log (Minecraft's default per broken block) * increaseExhaustionModifier.

increaseExhaustionModifier  default 1.0, min 0.001, max 1.0
This determines how much exhaustion should be added to the player per harvested log. By default 0.005 * 1.0.

increaseHarvestingTimePerLog  default true
If enabled, harvesting time will increase per existing log in the tree. The amount is determined by 'increasedHarvestingTimePerLogModifier'.

increasedHarvestingTimePerLogModifier  default 0.1, min 0.01, max 10.0
How much longer it takes to harvest a tree with 'increaseHarvestingTimePerLog' enabled. The actual speed is: newSpeed = originalSpeed / (1 + (logCount * increasedHarvestingTimePerLogModifier)).

amountOfLeavesBrokenPerTick  default 3, min 1, max 16
How many leaves should be broken per tick after a tree has been harvested. Increasing this will speed up the fast leaf decay, but costs more processing power per tick.

Axe Blacklist Feature:
It's possible to only allow certain axes to harvest trees. On first load of the mod a blacklist file is generated. It is located at ./config/treeharvester/harvestable_axe_blacklist.txt. This works for modded axe items as well.
