QoL: Blueprint shows inputs/outputs when zoomed out#2699

It’s hard to see directions of belts when placing platform blueprints zoomed out. The blueprint is either fully blue or belts are visible but impossible to tell directions. So player has to zoom in to determine input/output directions.

I suggest to add some visualization, like arrows pointing to and from blueprint tile, which would indicate whether belts are input or output. Something similar exists already for placed platforms but it’s not visible during blueprint placement.

Even more, I’d love to be able to include a direction as part of the definition of the blueprint, such that pressing the arrow keys while placing the blueprint orients it in that direction. When I’m placing other elements I use the arrow keys quite often to orient them the way I want, and it would be nice if I could somehow specify what the “forward” direction is in my blueprint so I could do the same with them.
