After taking notice to the changes to scanning I believe a lot of the same changes could be used in the PI UI. Some changes that would help the players and expedite the process include;
1: Add a jump to next extractor head button. I can not tell you how many times I’m just zipping around the planet trying to find my buildings.
2: Allow players to save extractor head formations much like scanning formations.
3: Allows the buildings to be selected in mass and moved to a new location keeping all the links and such intact, rather then tearing down and building new ones. A moving cost can be associated with this.
4: Have factorys auto assign a schematic based on what mat was routed to it.
These changes would save the players a lot of time and frustration. Please feel free to add your ideas as well.
