Simple Waypoint Datapack to set a location as a waypoint and teleport to it (works from any dimension)
this can be used in servers as well

"later i will update the datapack in order to be able to set any number of waypoints and teleport to it using a gui but for now its still under development"

Commands-

/function waypoints:setwaypoint
/function waypoints:teleportwaypoint

if the datapack lags you can tweak the particle effects in the files.
