Not sure if it has been suggested but it would be nice to have a "Logic" block that actually did nothing.... but was able to connect to another block like itself and create a cosmetic "PIPE" of configurable colour and width, working on the Helicarrier there have been numerous times where a cosmetic pipe (like the logic connections) would have been very useful, to be able to colour it to any block texture/colour would be awesome and also to be able to alter the thickness of it up to the width of 1 block would be great. Maybe even create Corner blocks so we could turn it nicely around corners too... just imagine corridors in the ships with pipes and cables running along the ceilings like in every great sci-fi film out there lol.
