Really?
What do you mean by 'really'? That hardly seems like a reply to the question haha.
Anyways, I'm currently almost at trial 4 and still haven't gotten any new additions to the bottom screen. Any PSS-like features like trading (Wonder Trade and GTS included)/battling people or friends are in the Festival Plaza, so I'm assuming nothing more will be on the bottom screen. Someone can correct me if I'm wrong, since I'm not very far into the game.
That means I wanna reply but I don't know cause I haven't got my copy.
