The Studio was built for a mouse: columns, a timeline with blocks you drag, a music strip. On a big screen with a controller in your hand that doesn't work well. So the Studio now has a second layout, made for playing from the couch.
Focus Studio Instead of everything at once, you see one thing large at a time. L and R switch tabs, ZL and ZR page through the parts of your routine, shown as large cards. The selected part gets its own card with the move, the length and the dancers. X opens that part's options, Y shows the stage, and + tests the whole routine.
Crew overview A separate overview shows what every dancer is doing at a glance. You immediately see where a canon starts, or where one dancer does something different from the rest.
Readable from a distance Cards are large and there is less on screen at once. Everything has to stay readable on a TV across the room, and on a small screen in your hands.
On PC the desktop Studio stays exactly as it is. The new layout is made for consoles. We're keeping those options open, and as soon as there's more to say about that, you'll read it here.
