I am writing you with connection the question upper. So I would like to ask you if is it possible to save selected selection of some node (group, image). Since I have dificulty when I select some selection by Lower or Rise selection (that option is accessable when the right button is pressed) than I save my graph and close. And the problem is that when i open again my graph the selection is not saved. So please could you help me how to save the selection of image, group and so on.
