After building a large multilevel ship and finding that I had to make a system of ramps to go about the floors, I began to think that maybe there were better ways to tackle the issue of traversing decks in larger ships. I came to the idea of a sort of "ladder" block that, when one pushes themselves against it, lifts the person up according to the gravitational field they are in at the time. If they are not in the influence of gravity, it will do nothing and maybe notify the player of this. I'd imagine implementation would be fairly straightforward compared to other, less practical alternatives, and such a feature would make building larger ships with proper interiors not a nightmare.
