Choose what you want to produce and this will tell you the main cause why you are not making more of it.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
I'm monitoring item X with WiM, and it tells me X is short because I'm short on Y. But it doesn't differentiate between "you don't have enough machines making Y" and "your machines making Y don't have enough fuel". I'd love to have an icon for this.
This is a good point, might be improved in a future update
