I know there are "walkway" blocks in the game, but they seem to be more designed for making outside access-ways to factories.
I like being able to walk around inside my factories and jumping all over the place is kinda tedious, plus not realistic.
It would be nice to build smaller but walkable catwalks that you can up and over belts with, or span across a number of machines/conveyors to get around/inspect the factory. Most machines seem to have a catwalk grating on top of them, I'd suggest making it align to that so you can also use machines with their in-built ladders to get up to the catwalks too.
