A rather simple mod to add, list and activate waypoints. Configuration is global, waypoints are per-server (multi player) or per-world (single player).
/waypoint name activates the waypoint called "name". If quoted, spaces might be used aswell./waypoint name x y z [world] creates a new waypoint and, if world is the same of the current one, activates the waypoint itself. World is potional./waypoint list/waypoint delete [name] removes a waypoint from the list. If the waypoint is the current one, or it's not specified, will also interrupt the navigation.Options (they can be configured visually. The UI is triggered by /waypoint or via settings -> Mods -> Waypoint)
/waypoint range [new range] sets the range at which the navigation ends. Argument is double./waypoint removeAfterReach true|false if enabled, the current waypoint will be removed from the list once reached/waypoint toggleAfterReach true|false if enabled, the current waypoint will be disabled, but will be kept in the waypoints list
