'Going Large' (in the sail presets menu) is not a synonym for running before the wind. It more properly refers to a broad reach where all sail can be set without shadowing. So this sailplan option should be renamed to 'Wind Astern' or the like.
Also, have you ever considered making the calendar 'wrap around?' I wanted to set out for a real time voyage with the IRL date, but that would have resulted in me sailing off the edge of the weather timeline in a few days.
