If no machine slider we have to calculate machine count to fill full belt.
also left and simple mode are useful.
Please back to 1.0.3 for who need that feature and let them decide settings.
I agree with the poster that the machine sliders were nice to have. I use them pretty often myself.
Also the machines in my save still show the results for the machine count i had set.
So if possible it would be nice to have the sliders back.
