Create Waypoints to mark important findings you’d want to visit later or teleport straight to the place. Being survival friendly, the addon is suitable for your single-player playthroughs. Craft a special item and get access to the special menu that allows you to place, edit, and choose the color for your waypoints.
The process of placing a waypoint is very intuitive. Use the item, and the menu will pop. Two options there: Add or Remove. When you choose to add, the only thing left is to specify a name, choose color, etc. If you hold Crouch and activate the item, a second menu will pop with all the active waypoints listed. You can teleport to any of them.
Experimental gameplay features needs to be enabled in your world.
