I don't know how many would find this useful, but I'd like to see it for my voyages: A tag that highlights when the engine is running. This could be generated by setting a motoring flag whenever the engine is running above a certain RPM, and the boat is moving. It would be assumed that IF a log is being actively recorded AND the engine is NOT running then the boat is sailing.
It would only be useful for those boats with the engine connected to the NMEA2000 network, and hence to SignalK.
I also might get a little bit more complex for catamarans that frequently motorsail on one engine. Maybe: IF (Engine0 RPM > X OR Engine1 RPM > X) THEN Motoring, ELSE Sailing
