Simple return conveyer

Like a current flat sorter, 1 in, 1 out and 1 return if the prio is full. then we can more easy automate belts to go into storage or machines and not stop the belts. if full, then return to sender. would make it much better and its an easy compnent. Even would be nice if balancers and sorters can be build on top of each other so the 2nd and 3rd line can also be sorted

The stacking of balancers is a must, that would in essence allow a belt system to be created to this idea. Also, balancers should have the option to double as sorters, similar to the game Dyson Sphere, where a balancer can act as a multi-directional multi-item hub allowing belts or pipes to remain on the same "layer". This may take some of the fun out of planning as we know it now, so many have this as an option pre-game.
