Tablet Dashboard Layout

Is there a better way to lay / set this out? So the navigation is fairly narrow to the left and the other section takes up the rest / most of the remaining space, or if not at least centre that section to the middle of the page. (I know I’m not using exactly right terminology but this was best way of me trying to explain.

You could try using sidebar mode - that will give you a narrow strip (on the right) and the other section should take up the whole of the rest of the screen.
