This Datapack adds the Ability to travel very fast between places you've already visited. You can even mark each Gateway with a Block to remember easily which Gateway you need to take.
Craft two Gateways and a Gateway Linker. Place the Gateways at the two Endpoints and right click bought the Gateways with the Gateway Linker. If a Portal isn't linked, it will cry, because it hasn't a partner ; ) .
To mark the Gateway you need to drop a Flint and the marking Block underneath the Gateway.
To remove the Gateway just break the Block underneath it. If the Gateway was linked to another, the linked Gateway will be removed as well.
The Crafting Table will show a Eye of Ender as result, but you will get the correct Item after you take it out.
If you haven't disabled the Tool Damage you can repair your Gateway Linker with Eyes of Ender. To get more Durability you can also enchant it with Unbreaking.
