Just as in real life having cows and llamas roam around would be a big nuisance. I'm all for strollers and think they should have been added long ago. A World editor would also be great. When you click on a place it says "go here" whether or not they walk or fly is dependent on what you have set as the preferred way of transportation and the distance. You can open the Fridge and drag any produce you have in your inventory to it. If a recipe calls for Apples and you have apples in the fridge or your inventory it will be used reducing the cost of cooking. The same goes for other fruits and vegetables.
I have not found it can do that on playstation. Also I'm not talking about roam everywhere. I just mean if you make a pasture thats fenced in they can freely move around their enclosure. I agree about the a world creator would be great. Also on the cottages and farming pack world in certain areas have unusable sheds and stuff and miles from other houses. The ability to enlarge land like that and if you have kids with kids be able to put houses for them on the property that they can solely use on your land
You can already build more than one house on your lot and if you so want you can have the kids in one and the parents in the other. A bit unpractical but you could do it.
