What would you like in Super Mario Maker? My most wanted thing is more Themes. We don't have Desert, Snow, Volcano, and Cliffs yet. Also their Castle and Underground counterparts. And to make it more compact, I'd set it up so when you press the Ground, Underground or Castle choices, a few more styles come to play, and you can use them as usual. And the counterpart included would look like a pile of Theme Pics. :)
