handful of peas

I've never played Rhythm Heaven, but I've heard it's kinda like WarioWare right? if this gets 20 yeahs i'll buy the game

Question: would it be possible to search for specific communities on 3ds? Also, when I view a comment and then back out of it, is there any way for miiverse to save my place in the feed instead of having me scroll all the way back down?
