i can not compare the same items, example:
i have copper on belt A and more copper on belt B, i can not compare how much is on belt A to belt B, it adds them, even adding a decider to output the input value to a new signal - outputs nothing instead
setting up a rail signal to the circuit network where there is only one rail signal on the entire rail, the rail signal doesn't work. instead blinks green, yellow, red, and does not close the gate based on the input value.
example, i have all my chests wired up to tell the circuit network how much copper is in them, then i set the rail signal to if i have more than this much copper in my chests, stop the train. instead i have to set the train to wait till the cargo container is empty before moving, or also set the train based on circuit network signal sent to the train station.
it would be nice to have a "not equals to" in the deciders as well.
