Similar to Maya (I think.), I think it'd be nice to know the perimeter in which the render is actually covering. I'm on a small 13" macbook and it's a waste of time to position model in the display, render check, adjust position and so on every time I want to render. If there were outlines in the view, showing the area that would be rendered, that I could also toggle on/off this would save time. The toggle could be in the menu shown in the image below. Besides this, thanks for making a great product.
