Quick Leaf Decay Add-on 1.20+

Sometimes it is necessary to remove trees from the Minecraft world to make space for building. To save time, players usually break the entire trunk, removing all the wood blocks so that the leaves gradually disappear on their own. The problem arises when you build a giant house and find that the leaves still float in the air. This issue can be solved by the mod Quick Leaf Decay: it significantly speeds up the time it takes for leaves to disappear after the trunk is removed.

Wherever you break a tree, the leaves will decay within 5-10 seconds. The add-on can be combined with others, and the function will even work on servers.
