To better understand importance to me: again this home has many
'courtesy' light switches. There are multiple switches to turn ON/OFF
the same light placed about home as a 'courtesy'. What I mean is, is
that the likelihood of entering an area, using the light switch,
exiting the area and using the SAME light switch is the most likely
pattern of switch use. Many of the rooms have more than 3 such
entrances/exits. and it is handy to be able to leave the switch in a
known pattern. During the day, it is somehow pleasing to look about
and see that all the light switches are in the OFF possitions,

So a few times a day go through the house and turn all the switches
down. If a light is on turn one of the controlling switches upside down
(only has to be done once).

If you want to know if the lights are on or off replace the switches
with switches that have pilot lights in the handle.

andall the little mounting screws are in the 12-6 position to add a
touch of neatness and professionalism to the installation. [the screws
were all placed in the identical positions by the original contractor,
which I interpret as a sign of quality workmanship and attention to details]

I certainly wouldn't interpret that as a sign of quality workmanship -
may or may not be.
