OpenHarvest is an open-source right-click-to-harvest-crop and tree-chopping mod.

It supports any crop that functions like vanilla crops, and isn't limited to crops that are fully grown at age 7, any age will work!

It also optionally supports chopping veins of logs that are oredicted. It doesn't need manual config log additions.

This mod doesn't even need to be installed on clients, it will work serverside-only.
