WaypointCrystals
About
A craftable waypoint teleportation system where any 3 identical blocks arranged vertically in a crafting table create a Waypoint Crystal. Players configure the crystal via GUI - setting a name, privacy mode (private/public/*********), and adding whitelisted players via chat. Right-clicking places the waypoint, and interacting with it starts a 5-second teleport timer that cancels if the player moves.
