I'm a solo player so this mainly comes from my experiences as a solo player.
I find myself sailing (slowly) into the wind for what feels like most of my voyages. I have two options. Slightly speed up my voyage by tacking into the wind. Or stand there. Tacking is tedious and I'm not even sure it speeds up the journey.
I would love for more little cosmetic things to do on the ship. Let me open and close the hatches. Let me swing around on ropes. Implement some type of solitaire card game in the captain's quarters. Give me more things to arrange and do below deck. Anything other than setting a course and alt-tabbing to entertain myself during the trip.
