With the addition of Astronauts, a ladder part would be great to have, one that allows the astronaut to interact with and use it to climb tall craft. The procedural options could allow the ladder to be a certain length and type.
Towers with lifts that can be used for Astronauts to use the lift to get into the module on top of a large rocket, with similar procedural options for height.
Stairs would also be nice.
