Please create a feature that can flip a selection of objects horizontally and/or vertically. It would help if There were several objects which we wanted to duplicate on the other side of a set of objects with the same line flows etc.
E←D←C←B←A to A→B→C→D→E
or
E←D←C←B to B→C→D→E with lines still able to attach to A on either side :-)
