Great app, needs improvement

I really do love this app and I think it has great potential, but it does need some improvement.
1) Make adding friends easier! I want to add friends but they have to be on Facebook or twitter or hey have to be with me at the time for the face-to-face option. Couldnt we add them using usernames instead?
2) The rooms! I think we should be able to choose what our room looks like because my room really doesnt fit me or my mii!
3) Lower prices just a little bit? They arent too overpriced but it is a bit difficult to make money in this game so I would lower the price of clothing.
4) Minigames that dont cost in game money! Even if you dont get prizes for playing it we need something to do thats not costing us
