Yeah, the port UI/aesthetics should be a pretty low priority thing until they've finished adding features that might require redoing the UI. However when its eventually worked on in some distant future, I kinda picture it being largely the same, just having a nice piece of artistic background similar to the Sid Meier's pirates games.
Again though, port UI is currently quite function and, as nice as it would be, prettying it up should be low priority for now.
