When you copy/paste an element which already exists in the graph, it will produce exactly same copy of that element, including the name. It would be more convenient if the new element has a distinct name.
I created metadata called 'customMeta'. When I copy/paste it twice then I end up with three copies of it, all called 'customMeta', but I'd like the first copy to be named 'custom Meta(1)' and the second one 'customMeta(2)'. This way I can always determine which is which.
