Right now, it is extremely difficult to get items to be in the same spot across screens and also the same size. It would be nice if I could explicitly specify the coordinate of a zone (e..g, 50%, 50% for the center of the screen) and the size of the zone itself (height/width). That way when I need things to appear on the same spot across screens I can easily do so, without messing around with copying/pasting from screen to screen (which is inefficient if other aspects or settings of the screen change).
