New feature demonstration: For tracking import flow to a slot

Short video clip showing new ‘import flow analysis’ feature in Production Line. The little arrow buttons change the ‘resource map’ to show (with green lines) where each resource will be imported from, updated once per second. Helps spot long import lines.

Coming in 1.81.

This looks good. Can def be helpful in large factories.

A quick question.
When a slot needs resources - does it pull from the closest supply stockpile?
Or does it give priority to stockpiles matched with slots?

For example supply stockpiles that are matched using the copy from slot feature.
Do slots pull from those first?
It “seems/feels” like resources from these copied stockpiles move resources faster.

Meanwhile my mini stockpile of 18 sensors just sits there full.
