By fulfilling certain requirements, you will have the ability to automate makers, you no longer need to manually collect finished products. To know what are required, you can tap a maker then the plus mark square on the right.
If conditions are met, the AUTOMATE button will lit up (otherwise it will be grayed out) and making money is only a click away!
Additionally, a plus mark will appear above the maker when you have met the requirements, tapping it will lead you straight to automation screen.
