Add a proof of concept for filtering the Dive List,

Press CTRL+F and a line edit will appear, whenever you write on that will
be used as a filter against all columns. The results are maybe somewhat
surprising in trip mode, but when sorting by another column this shows
some potential.

Hit ESC to remove the filtering.

I need to find a better position to put the Widget, but it's a proof of
concept.
