add some form of stations, which you can build around the map, and fast-travel between them on the Neptune rocket (like really fast), it will add some utility to rocket, and it will be easy to transfer big amount of resources (especially with new underwater elevator!), and its going to make Neptune not just the vehicle to beat the game (if we going to beat the game on Neptune), also its pretty fun!

(something similar to what we have in astroneer)
I don’t really think the map is big enough for this to be really necessary. Also, if any fast travel was to be implemented I think it would make more sense for it to be attached to the biobed.
