It would be great to have folders we can put past classes that are completed in to. I create classes on a monthly basis as we collect fees monthly and have around 20 classes a week so my class list is becoming huge. We send our invoices out around the 15th of the month so customers have two weeks notice before due date so I can't delete the classes when I clone/make new ones as they are still currently running. Once a month is completed it would be good that these classes could be put in a folder.
