Stack Number Mod for 7 Days To Die is a free and useful add-on that makes it much easier to harvest resources. It works as a one-touch button that allows you to increase the stack size of a number of items at once. This means that, when you're farming, you don't need to press the button every time you want to increase the quantity of a particular item. It's a simple way to save time and effort, especially when you're trying to farm an item that requires a lot of effort, such as an ore.

In addition to that, this mod also updates the blocks.xml file so you can farm to your heart's content.

This is a very useful add-on that can help you to save a lot of time.

The only thing to watch out for is that if you uninstall this mod all inventory quantities will be restored to their default values.
