Yes, not too much work

Could do this, but then I don't need the ImageListener. But the nice thing with ImageListener is that it uses the static field listeners in modul ImagePlus and hence works automatically on all images, be they open at plugin invcation or not.
Thats why I came up, rather naively, with the idea of proposing the ImageFocused event to be added.
I did it low-key, though (see subject line).
