I would like to suggest that when using a teleportal, players should first choose which planet they want to warp to and then list the available teleportals on said planet.

As more large planets like the starting one are added to the game, players may have multiple teleportals on each one. The current system lists all teleportals the player has ever created regardless of planet. I can see the list quickly becoming confusing and long.

This change is not required at the present, but it may be something that should be kept in mind for the future.
