Filter which classes are visible

As far as I can see… the only options to view are "ALL" or "EXAMPLE CLASS ONLY" I would like to see check marks beside the classes so you can select which classes you would like to view.

Also I can never get a pdf of the "ONLY" option to show up. it always shows up blank. but when I have "ALL" selected for the view mode then it works…

Thank you. Either way the site is very helpful! I am so appreciative of what you all have done to make our lives easier!

GOD BLESS YOU AND YOUR TALENTS!
