yes, that would be great.
it also would be great if we had some mod option whether currently inactive smelters (which currently cause a warning message "xxx smelters have no recipe") should get a default recipe (eg for iron/copper; or maybe even a mod "per player" setting to use it "on the go" with a choice of what type to assume) if currently nothing is smelted. in a setup for smelting steel, bricks or anything else those values probably will be unusable, but in most of my setups i have to clean smelters and manually add ore to be able to use this mod to calculate throughput of a smelting+assembler or even mining+smelting+assembler setup.
ps: this mod together with bottleneck and utilization monitor is one of 8 mods on my "QOL-MUSTHAVE" list that i use on ALL maps that i play :-)
