See hiatus in tracks

[domiriel]

In some tracks, sometimes the signal is lost and there is a bit without actual points. However, in the interface, you get a line connecting the endpoints of the discontinuity and it becomes hard to see where those hiatus are. Maybe highlight them visually somehow? Say, a thinner, or dotted, line instead of a solid one? Everything else would remain the same, but this would give some visual feedback on parts that the user may want to pay more attention to to complete the data (and maybe get auto suggestions from the system, if it is a long stretch).

Could be turned on and off in a settings panel?
