/gamerule TrackLocation

There should be an option to track specific teams or players using the player locator bar.

This makes it so players aren't overwhelmed with unfamiliar player icons and could make competition between teams more fun since they don't know each other's whereabouts, which would be perfect for mini games.

/gamerule TrackLocation Team [Team Name]

/gamerule TrackLocation All
