Once you get more than a few ships, it becomes a necessity to manage your ships through the Ships screen. I like being able to see all my ships here and sort them based on the different stats. One thing that would be very good to have is an icon to indicate that a ship has been grappled.
For example, in the below screenshot, the Sunken Scoundrel is grappled. If I were to slide the ship over, I would see that the upgrade arrows are unavailable, but it would be really nice if there was a little icon on the main page that showed me the ship was grappled. It looks like there’s space next to the attack/move icon. Perhaps a small image of the Grappler himself could be added there?
