Problem: When an instructor looks at a group set, all group numbers are collapsed. Once has to uncollapse them one at a time to know the name of the student participants in that group. Imagine having a class of 300 and you have groups of 3. You will have to do this 100 times, not just once, but every time you need to do this in the semester.
Goal: The proposal is to be able to collapse and uncollapse a group set group numbers with their corresponding members with just one click.
