When rotating an enlarged plan view, the current interface requires selecting the crop box then rotating the box in the opposite direction of the desired plan rotation. And if the crop box is not square and the rotation is 90 degrees, the revised crop will be 90 degrees out of whack with the desired view. All of this is highly unintuitive.
Ideally, when the crop box is selected for rotation, both it AND the view contents would rotate TOGETHER, like rotating a photo (or any graphic) in a page layout program. This would save endless hours of user confusion not to mention crop box resizing, gridline dragging etc.
