double post, but with the amiibo cards. You should be able to with most of the normal villagers once you import them with the amiibo card function can bring them into staying in your village.
other amiibo card characters such as kk, lottie etc will just appear and give you a gift.
Also in the original touch screen once inside your house you only had the option to turn on / off the room lights.
In the update you can do more, unlock storage space, and re arrange furniture with the happy home designer drag and drop feature. Plus things like cushions can stack ontop of other furniture pieces now but you have to play around and see what works and what don't.
That little icon at the bottom right screen will allow you to post screen shots you've taken onto social media such as facebook/ twitter.
