Well my suggestion is that I would love to have an button to like show an icon hovering over the hearthlings head or something that indicate who it is or atleast indicate what class they currently have, small feature that i personally wolud think will add better to see where the respective hearthling is 
and another, like at start you make alot of one furniture like a mean bed sibce you dont have much materials for others at start, what I would like to have added is a way to fast change every furniture like a mean bed to a compfy bed that the hearthlings switch automaticly, like they look up where mean beds are and change them to an upgraded version when you can build them.
thx ^^
