Add ability to archive classes

I really like the functionality of being able to use KA with my students. I like being able to follow along with those students over several different years, and for students that I get multiple different times, due to me teaching different math classes, I like to be able to link up what they did in the past with me with what they are doing now. I also like being able to go back into my old classes to pull out key things that I curated over the course of developing a class. However, I wish there was a way to "Archive" old classes. This would allow me to still access those things without having 15 different classes on my main teacher dashboard. Google Classroom does a nice job with this and I would love to have that same functionality extended to I platform that I have loved and used since around 2008. (Made myself and account in 2011...would be closing in on my 3rd sequoia badge if those stacked!)

Best!
