TL;DRAllow showing the (production) statistics per surface.
Not sure if the data is already in the game or if there's just the global data. If it already exists, this is only a UI feature.
What ?Take the following window: It would be nice to filter those statistics (mainly production, maybe fluids and others) per surface.
This would only show the production/consumption on this surface.
Why ?There is a popular mod called Space Exploration which adds planets and inter planetary logistics. Those are implemented as surfaces.
It would be useful to see what a certain planet produces/consumes to further optimize the factory. Just global statistics don't show the full picture here.
