Using hovering hands, which are incredibly expensive, for intersections and bridges is definitely not the best way. The automation line for brass and light gears is way too big.
Items can't turn when the conveyor belts are adjacent to each other. You have to partially place them on top of each other which is kinda finnicky as too much overlap due to space concerns will not work.
You should specify the default mode in the description, because after testing the other mode, it does indeed work. Maybe the soft mode should be the default mode as its much more common.
Ok, I forgot about the shift hot key for the logic gates.
