Have been playing around trying to come up with something myself, but the skills are, shall we say, "somewhat lacking"
I realise this game is in the very early stages of development, but as these systems are pretty much an integral part of almost any starship design, thought there would be something simple in place to address this need.
We have the "plex-lifters" for stations, and my thought was if these could be used on ships, made directional, and able to be controlled with logic....presto.....one multi-directional elevator system.
As I said, my knowledge is fairly limited, so there maybe issues with this idea that I am unaware of, but surely there needs to be something a bit better than the "gravity lift" idea I found on you-tube, which seems to be the only option out there at the moment.
