SimpleHarvest Mod 1.18.1 and 1.16.5 adds right click crop harvesting, configurable via JSON files. This mod does not need to be installed on the client. Only one thing that is missing from the client side will be the ability to swing your arm after harvesting a crop.
Harvesting is made much easier with this mod. Even though harvesting is not difficult, it’s still a very real task. Sometimes you may harvest a tree that is not fully grown. This basically means that you lose what you could have harvest if the tree was ready for harvesting. A common mistake is when an overgrown tree is cut down and becomes unusable. These errors do not affect your game in any way, but they can be frustrating.
Modifying the function to the right click reduces harvesting errors. Because attack and block destroy are located on the left click, this mod minimizes harvesting mistakes. There are less chances of making mistakes that could be very frustrating, so it is better to move the harvesting functions over to the opposite side. It also offers additional features, such as the ability to avoid harvesting the wrong crop or only harvesting when the trees have fully grown.
