For the locator bar add the amulet from mcsm

In my opinion the locator bar is a little overpowered I know you can turn it on or off but to balance the game a little you can add the amulet from mcsm which in the game is used to locate player from a long distance it should be made with a eye of ender in the middle gold ingots in the corners and in the remaining slots there should be a diamond an iron ingot redstone dust and an emerald when you hold it in either your hand or offhand it replaces the xp bar with the locator bar and like a lodestone you can click on player to add them to your bar and double click to unadd them that way some players don't instantly get tracked down on a server if they want to remain hidden this also allows groups to be made so you can have factions that can see each other but not the other factions when you add someone to your locator bar any other amulet you pick up will still show your locator bar only so if you pick up say someone else's amulet you don't get their list of added people and when you die you can have a spare amulet at base to find your friends
