And oh, by the way. We need some decent explanation of what exactly this
visualizes :-)

 on the *Dive Profile* is an instantaneous reflection of tissue pressures at 
the moment in
 time, at the position of the cursor on the dive profile.

This adds a paragraph about the heat-map to the user manual. Of course, this needs an updated screen shot as well, Willem?

And we should better replace the icon as well, let me see what I can do there.
