I'd like the idea of maybe battles and rare hunts showing up in the Airships. Maybe you could choose to have the express travel (would be a small cutscene) or a scenic travel, which would be the one where you wait for the airships to dock. And that woyuld have raids and whatnot. Rare beasts maybe, like the kracken that used to be in the ships in FF XI.
But just a thought.

And being able to see the chocobo timer, how long they're summoned would be a good idea.
(I don't have opinions for the other things as of yet)
