I have done a search of this section of the Forum and nothing came up - so here goes.
Now we have the ability to turn stations on or off, we often require to read the contents of the loader chests.
I usually use bot loaders in late game as they have space advantages over belt systems.
Currently this means that you set the circuit to read the contents of the requester chest.
Unfortunately this means that you cannot use the Set Requests side of the circuit control of the requester chests.
It would be really handy to have two circuit connections on requester chests - one for input (Set Requests) and one for output (Read Contents)
This would allow the switching on and off of stations/signals based on chest contents, whilst still able to control amounts and items via Set Requests.
Obviously you would use the red and green wires respectively to make the connections.
