It's just what some people like to do on these forums, no harmIt starts to sound a little... desperate.
You're right it's not egregiously bad. But out of interest I just had a look, I reckon you could get the 3 Control Center panels (Main, Audio, Home) as they appear on 4.7" iPhone portrait to fit into the 9.7" iPad portrait screen space, all at once without needing to swipe between them, bearing in mind you don't need to duplicate some of the side margins when they're next to each other and you could possibly go edge to edge as there's nothing else to scroll through. AFAIK iPad Mini has the same relative screen space, it's just smaller, so that works for that too. If you can fit it into portrait then it follows landscape and 12.9" should be easy too.
That just seems like a simple little improvement they could do to make the most of the extra space. Tada
