Hi john
Funny you mention that as we have actually tried that in vfx, but I found myself getting frustrated that often used controls like the back button were either not where I expected them to be or were off-screen, so I've decided to go with static controls, as I prefer function over form.
It's a valid comment though John, I also thought it would be a good idea and I think there are other manufacturers doing this, I think NSM does a vertical jukebox with this setup ?, you may correct me on that one ?.
