I would love to see, as I'm sure others would, a "Protected View" option for dashboards.

This is important for not only preventing others from modifying a dashboard but in particular for better usability. When using dashboards on a touch screen device, the narrow margins between widgets and the outer perimeter of the dashboard viewport, combined with the necessity of having to touch the screen to scroll, make it *very* easy to inadvertently move or resize a widget when attempting to scroll.
