Unfortunately, I am not at InstCon. However, I do have something that might be something to discuss at HACK NIGHT (instcon15)
When the Links section (Files and Images are the other 2) is selected, you have a list of content down below it. You can click on the arrow to expand the listing below the heading. However, you cannot click on the arrow of an expanded area to collapse it back. You have to select another area and then it is expanded. The expand and collapse by clicking on the arrow works when in the files area, and I do not know about images since I have no images uploaded.
The image below shows an expanded area, and clicking on the down arrow by Quizzes does not collapse the quiz area.
