It's great that smaller buildings show expected output per min such as the furnace or splitter (30/min 15/min etc) - but not all buildings don't show this, which would be nice to have that. So when making basic cores, how many per min should be being created. Since you also need the drones for delivery, the drone hub should some input / output of resource as well vs drone time which is hard to calculate.

Essentially put the input / outputs on all buildings and show in real time along with targeted output/min. You could either show this on hover/click on building or efficiency view, so can see from furnace, splitter, core, drone, and finally out to bot assembly how much is flowing through each point. Then you don't have to guess based on belt and crane.

Satisfactory does this well by showing both needed input per min and how much you're actually giving the machine and outputing.
