We recently held a MCS workshop in Costa Rica with MPA park authorities, fisheries authorities, and the Coast Guard. We showed how you can download a csv of vessel tracks and one of the fields included was the heading of the vessel at a point in time. They expressed that it would be useful for them to be able to visualize heading directly in the map. Perhaps it could be an additional timebar setting like vessel speed, or be a field when you hover over the track. Also, related to the time bar, some people were confused by 'Vessel depth'. I agree that it's not super obvious that this means bathymetry at the location of the vessel. I'm not sure what a better 2-word option would be, maybe 'vessel bathymetry' or even just 'bathymetry' would be clearer.
