Using Student Groups and Dividers in Progress and Plan

Hello, I'd like to suggest the ability to select only a specific group from within my classroom when I'm in Progress and Plan view, so as to limit the amount of visual information on the page; alternately, it would be extremely helpful to be able to place several dividers (for example, a thick, dark vertical line) between the students so as to help me keep track within the table - I believe this could be easily incorporated in the "reorder children" dialogue box. Thank you for considering this.
