Users want to reach more items in left panel (places, folders, etc.) but don't understand invisible lines, so don't know they can move to display below section bottoms. STEPS TO REPRODUCE 1. Use low-to-medium resolution monitor (1920x1200 this time) 2. Users look for more items. 3. Users can't find them. OBSERVED RESULT Users don't understand panels with invisible lines (even w/visible scrollbars.) EXPECTED RESULT There should be option for lines between sections to be VISIBLE (not only dots--too faint) like classic file managers and HTML frames.
