The current method is functional. When the station is in stocking mode, owners can reduce the price of ores or whatever they are stocking with 1. When employees/miners are finished stocking, the prices are then reset to their margins. There are exceptions, but that's how I'm used to doing it.
This tool erases that process. Now, POB owners can profit off of employees or independent workers while employees and independent workers can see what their earnings will be at the time of sale while not having to change the price at time of sale. I really like the toggle option since the game does not provide the method to provide that information. It will take some getting used to, but once incorporated into a habit, this will be a valuable tool for POB owners who rely on mineable ores to conduct their business.
Very good change is good!
It ain't about what you are capable of, it's about what you're willing to do.
