Hey, I would like to suggest enabling or adding an option to enable the possibility to control the loaders with the circuit network.
Starting with Factorio 2.0 its possible to use the circuit_connector (AAI uses core's circuit_connector_definitions to build the vectors, see https://github.com/wube/factorio-data/blob/master/core/lualib/circuit-connector-sprites.lua#L100) and circuit_wire_max_distance (AAI sets it to transport_belt_circuit_wire_max_distance) to support the circuit network functionality:
