I find that having the control buttons in the top right corner a pain.

Most of my work is done on the left of the work space and in the middle area of the page being worked on. To have to repeatedly go to the top right to use Save, Preview, Page Navigate & OK/Cancel buttons is a long way to move the curser.

I feel it would be more user friendly, especially when doing multiple page edit/creation actions, to have these buttons down the left of the screen. There is plenty of space below the Home, 1, 2, 3, 4 & 5 buttons. The work area could then be extended upwards to give a larger working page.
