Thanks for the suggestions, Steve. We agree, that this could certainly be improved - especially when you have lots of vessels.
We also have plans for Custom vessel groupings which you could define the order that they show in, and could let you decide if you’d like the group shown in the visualisation or not. If it was shown, there could even be an option like, “Show this next to the previous group or below the previous group”.
I’m sure we could add some of the other information in the hover message (e.g. in-vessel time) to the main table too.
