This is a mod that I would make that makes the Eyes of Ender and the Sacred Eyes (if you have Legendary Beasts) have a different mechanic. Eyes of Ender have a durability of 25, and Sacred eyes a durability of 100 (keep in mind that Sacred Eyes are not craftable; you must kill Legendary Beasts to get them). When used, the eye would lose some durability, and a 50-block long arrow will appear pointing to the relevant location, instead of that throw-it-into-the-air-and-hope-you-find-it-or-even-see-where-it's-going insanity. The arrow would fade after 5 minutes. Note that Eyes of Ender now require 8 Blaze Powder because of their greatly increased usefulness.
