I use Graph for much of my school assignments, and it works really good. Often I will present my graphs for the class. Sometimes I have several different sets of graphs for each assignment and when presenting a new assignment I would like it to be easy for me to disable the graph elements currently shown and enabling the new graph elements. Today I need to click a checkbox for each individual graph element. I thought it could be useful to be able to group graph elements into folders with checkmarks on the folder level controlling whether all the contents of that folder is enabled or disabled. See attached screenshot for a suggested look.

What is your opinion on such a feature?

Cheers
