Horses

So uhhh i had an idea abt horses. I think there should be a wagon filled with barrels which only horses can pull. This could be a way for adding inventory to horses like we already have with donkeys or mules. Additionally, i think that when horses are paired with these wagons, they should be unable to move by themselves and only move while you are riding it. This is because the wagons will make horses to big to fit in traditional stables built by the player. The inventory size that i suggest for this wagon is one barrel space.
