I would like to see the replicator having a redstone control feature ( i see that it can use the redstone inverter upgrade but i have had no response from it with it in or not with redstone on/off)
i suggest that on a redstone signal the replicator starts a single run of whatever it has set to produce, if the redstone signal stops before it finishes the item it continues for that run then stops, if the signal is still on when it finishes its current run it starts another, therefore any single pulse shorter than the runtime causes a single item to be produced, and a constant signal causes the replicator to run consonantly, with the inverter upgrade ofc inverting this effect (always running unless recieve signal, finishs current item then shuts off until signal turns off)
