TL;DRIt would be very helpful if machines listed the items per second throughput information for all of their inputs and outputs.
What ?In either the sidebar you get when mousing over a machine or somewhere in the machine info window you get when clicking on the machine it would be very useful to have for each of the inputs and outputs how many will be produced / consumed per second if it's fully supplied.
This is similar in principle to the throughput info on the belts.
These should be the all in numbers including, number produced / consumed by the recipe, recipe time, machine speed, the speed and productivity impacts of any modules and beacons.
Why ?These numbers are fundamental to working out good ratios of machines to each other or to belts.
How many red circuit factories can I feed from my copper cable factory?
With this info you could put one of each down, see that for my current build the cable factory can output 7.5 per second and the a circuit factory needs 0.2625 per second so the answer is 28.
And yellow belts already say they are 13.3 per second so we're all good there as well.
Without this info you have to work it out every time, all the time, with spreadsheets even.
Cable is 2 per run, 0.5 seconds per run, and I have it in a speed boosted lvl 3 assembler so... 2 / 0.5 * 1.875 = 7.5 per second.
Red circuits are 1 per run, 6 seconds per run, I have them in speed and productivity boosted lvl 3 assemblers so... 1 / 6 * 1.125 * 1.4 = 0.2625
I couldn't even begin to count the number of times I've messed this up.
Incidentally the inspiration for this was watching Xterminator mess it up in his latest series https://www.youtube.com/watch?v=3igiUF8xeqk
P.S. I see now that the numbers above are wrong, I cause I messed it up again :/
