Light pink = no road need'd
Light grey/blue = need roads
Light Blue = onscreen @ 100% zoom
Red = MH
(each is a 5x5 on real map)
Not only are roads a concern here, but tall-ness of bldgs,
and the fact of which stuff needs click'n, and how often.
I try not to block bldgs from sight, so tallest -> shortest ( NW -> SE )
and clickable bldgs are always onscreen to click.
Manufacturing, residences, workshops, Training, will be the blue part.
those are < 3 hr clickable bldgs... Sets and Evolves can be grouped
together cause those are 24/48 hr collects and don't need to always
be on my screen, and can also be on the periferal.
