I just wish they'd give an option to decorate your roof with holiday lights when all the trees have decorations in December. I think it'd be cool if they'd update the game again and add new features like that one. Maybe you could buy it from Tom Nook as one of the exterior style things through December. I always see pictures on tumblr where they've photoshopped the lights on and each time, I get excited because I think that it's something you can do in the game lol!
