You can use the Journey plugin to find the fastest way from place to place.
Note: There's a slight bug with the setup where it'll tell you to go through 0,0 then back to continue navigation, it'll be fixed soon.
There are two main commands you'll likely use.
/jt - Opens a menu that shows all the waypoints you can navigate to.
/jo setwaypoint NAME - sets a personal waypoint.
A few other commands that would likely be helpful are:
/jo waypoint NAME unset - Deletes a waypoint.
/jo waypoint NAME public true/false - Sets whether everyone can see the waypoint.
/jo waypoint NAME rename NEWNAME - Renames a waypoint.
