Compact and UPS-friendly 1x1 loaders. Works with train cargo wagons, circuits, filters, and modded belts from Bob's, Krastorio, FactorioExtended Plus, Space Exploration, and Ultimate Belts.
i noticed that with shift+RMB / LMB, you can't copy and paste the circuit condition from one loader to another. you have to setup each single one individualy which is pretty tedius.
