PixelPonies

This plugin will give you information about a horse when you hit it with a lead. You can also get the information about the last horse you hit with /h info. /h edit lets anyone with permission edit the details of a horse. The data held about each horse is it's gender (and if it's a gelding), breed, jump height, name, and show name (which gets set as the display name for the horse). Horses will only breed with horses of the other gender.
