My institution uses Moodle and we have just set up our LTI 1.3 integration. I am testing before we implement this across all subjects next semester and want to know if there is any way to expand the rubric manager pop up when creating/adding a rubric for a new assignment. I have attached screengrabs of my screen to show how the pop up remains small no matter how much i expand the size of my screen. When i open a rubric i can only ever seen the criteria column and one other column at most. I have to scroll sideways to see the other columns, but again can only see one at a time. I can't see any expandable function in the corners of the pop up to allow me to expand. 

It would be so helpful if i can expand the size of the rubric manager so i am not limited to looking at only a fraction of the rubric as a time. I feel like i can barely see what i'm doing! Thank you.
