I will probably be shouted down but I would make all the buttons programable so that we could put what is most useful to us in the most useful places. My daughter is a professional photographer and has very small hands, its enough to cope with that the camera is for her very heavy, especially when equipped with the best glass and having the buttons fully programmable would make life much easier. I have to say it would also be helpful to me as it seems each time Canon bring out a new camera the buttons have moved and we start all over again.
