This is a small build to add a single much needed improvement; Split stack!

You can now shift-click a stacked inventory item to split the stack in half. The separated stack will appear in the same inventory if there's space, or your other personal inventories or active storage chest. The stack will drop to the world if there's no inventory space.

Hopefully this makes creating charcoal much nicer! And you can now share resources easier with your friends too.
