The mod adds some features that some casual or not-so-casual players lack. All functions currently available:

• Return arrows after target's death (but without arrow's potion effect, could be configured in future)
• Extinguish entities with water bucket on RMB
• Faster boats (with max speed and coefficient configuration)
• Mobs pushing (for transporting and other purposes)
• Affordable "Miner" enchantment (I level gives ability to mine 3x3x1, II level gives ability to mine 3x3x3)

You can configure it in-game by pressing Y or rebind the key in settings.
