Well, I don't know.
Scenario. I keep doing boat dives to the same sites (we'll be in Palau the
fourth time this fall and I bet we'll go back to the Blue Corner and many
other sites we've been to frequently). I use the phone app to track GPS
points, anyway, and download them.
Now I have a site with no name and a GPS location (well, I won't because I
always do names first before downloading GPS, but Linus and some others do
it the other way around).
So now Subsurface showme that this was really close to the Blue Corner and
I say "right, I remember, we dove the Blue Corner today".

Now if I want a new location because it's a different boat anchor point, I
completely type in Blue Corner and save that. New site, same name, close
by the others.

Or I just want to pick the existing one (or one of the existing ones, I
have three distinct anchor points for Blue Corner because they are
different dives, depending where you start). And I get the GPS coordinates
from that dive site that I picked.

The interesting question is "assuming I have GPS data, assuming I remember
the site was also called Blue Corner, assuming that site is in Hawaii,
should the Blue Corner from Palau even be offered as completion"?

I'm leaning towards "no" (not knowing how easy or hard that would be for
Tomaz to do). At the very least it should be marked differently in the
completion list if possible... maybe the completion list could add
distances if both the current dive site and the completion dive site have
GPS locations.

And here I go again, coming up with fun ideas to distract Tomaz from doing
what he's working on :-(

Existing. See above. You pick a site, you use those coordinates.

See above - we should give the distance and let the user decide.

After talking to Tomaz in a hangout I have learned that that is very hard
to do on the completer (as that is just text based). But of course if the
user has Marble enabled then they can see the dive sites nearby on the
globe.
