I didn't even realize we could change the theme until I saw this post, and then had to look all over for where to do it at!I changed over to Year of Luigi... I like it, mostly. I think I'd like it more if there was a darker, more neutral shade of green (Maybe a grey-green?) as the background instead of the Dream color thing. The Dream colors also don't go to the bottom of the screen for me, so t looks a little weird? A solid color might look better. It's a little bright... Green IS my favorite color, but I'll probably change to something else because it's so bright.
