I have been working on a large compound for doing ship development and such and been using your catwalks all over the place, but ran into a minor issue. There are several places where I would like to have just railings without the floor platform.

This suggestion is for just that. A railing (the same one used on the catwalks) without the floor platform that would seamlessly fit with the catwalks.

Another would be what I will call inverted catwalks. That is to say, the catwalk is right-side up, but, the walking plate is position at the top of the block space instead of the bottom. While keeping the railing at the same height as before for seamless transitions.
