Better Input output identification

Just wanted to suggest that it would be great if the buildings could be marked better/more clearly showing where the inputs and outputs are located and which side is which. I keep placing buildings and having to demo them because I want the input/outputs on the other side. It's obviously more of a problem the further out the zoom is, which is where I generally have it when I'm doing (or trying to do) efficient layouts.
Thanks for the awesome game, devs!! I love it...

I think this should be marked as DONE.
