TY for building this awesome game! Major timesink :p.
I have one small tip that makes life a lot easier and should be pretty easy to implement.
Currently it's not easy to see if the object you want to make in your inventory is already present in the logistical network.
Can you put a line in the tooltip of that item indicating its in the network? Or maybe have a green highlight around it when is in the network and a red one when it isn't?
Just a suggestion

Keep up the good work guys!
Greets,
