Mix of both probably. Star Wars tech seem to swap gravity direction easily and smoothly. Like the gun chambers on the Millennium Falcon.
I’m not sure about actual functional definitions, but I think of it based on the size of the various cities involved. Metro seems to be used when referring to relatively large cities and towns that have blurred together to the point you move between them without distinct separation. Whereas Greater is applied when there is still a more clear separation between the core “big city” and the suburban towns around it.
That doesn’t really answer my question. How does one get ublock origin on mobile?
