When rubrics are enabled and marking using the pdf annotator. If the rubric is any more complicated than trivial, there is very little room for it on the right hand side of the screen. The popup view is useful but appears to be fixed and, worse, it obscures the submission that you are marking.
Ideally, it should be possible to drag this to a different location. Even more ideally, this would work for dragging onto a different monitor if so equipped.
I might be saying that this should be in a proper window rather than a JS popup (which I assume it is now)
