I might be missing something really basic, but I'm sure there used to be a way of prioritising ware delivery and transport. I'm not talking about "high" priority within a specific building for construction or production, but for delivery across the whole map.
If I have some farms that are far reaching from my mines, for example, then I want to globally prioritise the delivery of beer and wheat/bread ... and at the moment my boats do carry these wares, but not very much of it.
I'm sure this feature used to be in Widelands ... or perhaps I am just confusing myself with memories of Settlers. Can anyone anwer this question?
