Factorissimo adds factory buildings to Factorio. Place them down, walk in, build your factories inside!
Mods introducing new content into the game.
It would be cool if trains could drive into a factory.
I know, right? I'd have already added that feature long ago if I could, unfortunately it's very impossible to mod in.
I mentioned it in another thread, but what about Factory Chest connections being able to connect to Cargo Wagons that are directly next to a Factory?
