It would be great if there were more accurate versions of /tp and /tp_to so you would teleport in the exact location of other astronaut...sometimes it takes a frustratingly long time to get to the player when you are in different points within a sector. Also, it would make it more handy to tp players out when they've got stuck underground or inside a planet core.
I understand there can be problems when you teleport a ship into another ship and that's probably the reason such command doesn't exist. But I'd trust admins to be that wise they'd not use it inside a ship core.
