This 7 Days to Die mod allows you to press E to pick up wild plants (like aloe, yucca, cotton, corn, etc.) that growing in the world. But It doesn’t edit plants that the player grows. You still need to punch those in order to collect them.
Simply download the zip file and unzip it into your 7 Days to Die/Mods folder. Your full path should be \7 Days to Die\Mods\KHPickupPlants
The forum topic of the mod is here.
