Well, I had a few ideas for the quiver, which was planned for Minecraft but was left out...
1: Custom arrows can only be fired by placing them in a quiver, think of it as a way to select what kind of arrows you want to use, If custom arrows ever enter the game, such as flaming arrows...
2: Arrows must be in a quiver to use them in a bow.
You Know,All The Ideas,That You Thought Of Seem Horrible And The Quiver Was ONLY SUPPOSED TO BE ADDED FOR HAVING SPACE FOR ARROWS,SNOWBALLS AND EGGS. Just Just These Ideas Are Bad
1: Custom arrows can only be fired by placing them in a quiver, think of it as a way to select what kind of arrows you want to use, If custom arrows ever enter the game, such as flaming arrows...
2: Arrows must be in a quiver to use them in a bow.
3: More than 64 arrows can be in a single slot.
Rate which you think is best!
And idea three is what you said, and the other are just ideas, so stop making an idiot and a jerk out of yourself...
