Publishing apps for just our class to see?

Is there a way my students can publish their apps just to our class. Right now I have them add the link to their app to a document, but I’d like a smoother way – an area of shared apps that is just for my class’s section.
Also, I’d like the kids to be able to save an app in the class section area, then modify it but be able to bring up the old version. Sometimes I want them to be able to compare old and new work, and if they can bring up both versions at once that would be helpful.


I don’t believe there is anything like that in place currently, but it wouldn’t be a bad idea to email to request that. They keep track of those kinds of requests and can let you know what the possibility of adding a feature like that would be.
