Subject: Teach the thing to actually track the currently selected dive
X-Git-Url: http://git.tdb.fi/?p=ext%2Fsubsurface.git;a=commitdiff_plain;h=2044dabc81062c22c7f95a2e0e57f931cee0205f

Teach the thing to actually track the currently selected dive

.. and repaint the profile when the selection changes.

Now, if it just wasn't so ugly, it might even be useful.  Except it
obviously needs to also show all the other dive information.  And allow
the user to fill in details.  And save the end results.

So no, it's not useful.
