That's how I always use it. But I haven't been on a boat dive since all
the changes to the dive site handling, so it's entirely possible that this
is currently broken in creative ways :-(

The way it SHOULD work is that if it has a fix during the dive, it takes
the first such fix. If not, it tries to find a fix before or after.

I can stare at the code a bit to see if I see a problem, or I can add some
verbose debugging option that allows us to see which fixes it picks and
why.

I don't think I'm good enough with Qt to whip up the UI that Linus
envisioned :-(
