The wall with the conveyor snap point perpendicular to the wall, I would like to see, maybe as an upgrade, a wall that could have more than one conveyor snap point on it. This way you could have a wall conveyor with up to 3 snap points total.
I like to run my conveyors around the walls of my factory if possible, with a multiple conveyor wall, you could have the belts come in through the walls with the 1, 2, or 3 holes through the walls, then curve them onto the perpendicular wall mount, this would keep the belts nice and neat, and would also mean that when I am feeding manufacturer units, my walls and floor to floor heights are not 4 high, just to get all the material around the walls
