Good afternoon.
Please consider adding an option that allows you to select the amount of resource produced (output stream per second).
For example, the speed of a high-speed conveyor is 45 items per second(or 2700 per minute). One electric mining drill with three speed modules, gives out 2.5 resources per second. It turns out 45 / 2.5 = 18 electric mining drill.
That is, the user can choose not only which electric mining drill to use, but also indicate which modules will be installed in it(including the number of modules), as well as request an output stream.
I hope I explained clearly.
