The peer issue can be seen in the bottom right, it seems like this isn't there intended use however I think it'd be cool! (Also the peers can't connect to the fishing house )
I made my first island and I really love it, I think on top of what I've already suggested maybe (down the line a ways) add an easy way to take your island and use it as a wallpaper. Hope you don't mind how much I've been making suggestions.
