it's also very irritating to see every. single.. mob... with hats!! I would rather see just a few mobs have hats, and that the harder to fight mobs, have the more rarer hats.
it'd also be nice if you could share your collected hats with others, and if the hats would have certain stats or buffs or whatever, you could trade them with others like trading cards or something lol
*ahem* take a minute to read the config, you can change the percentage
