I don't know how I got that detail in the status screen and I've not managed since. As it happens I had my camera with me at the time. I think I found a bug in the system somehow...
Yep, there are no side-to-side controls. That screen is obviously one I wasn't supposed to find.
I find the controls pretty good, I love the 'one button demist' for the front screen. I agree it's a bit of a pain having to keep pressing the 'mode' button to find the right ventilation combination though.
