A bridge of conveyer belts that vertically crosses over another belt lines may add possibilities of factory set up.
Another thing to add, it’s hard to use one INPUT line into multiple machines at once (since it needs more splitter and makes it annoying to make them connect)
Anyways these are my only my suggestions because I love this game. Thank you so much 
Some version of crossover belts would be an excellent addition. They could either be full 3D planning with high and low belt tracks that can be placed over/under each other (including up/down ramps to transition between) or it could be a simple unit that never stores a product itself but will move the product from one side to the other whenever space is available
Currently, we only have a straight conveyor belt and a conveyor belt splitter. How about making more belt types, such as arc, S-shaped, and more. That could bring preserve more spaces for other industry lines.
And also, the machines and belts look too much like toys, adding varied materials and making it bigger and thicker would be more realistic.
Hello, I tested the new production factory update and I didn’t find a way to intersect the conveyor belts to optimize production.
My suggestion is to add more conveyor belt shapes, such as ramp conveyors, to increase their height and be able to cross between them. This will provide many more possibilities for optimizing production and make the investment viable.
