M:EE Realms Plus implementation possibility

Possibly making it so that the player (students/teacher) can "Create World In Realm" or "Create Temporary Realm" in lesson menu when they have a current assignment that they need to work on, moving the old realm to the local storage for later use if needed. This could also allow the world to be entered by the teacher for aid in projects/ feedback from their "Invited realms" list to work at anytime even when on a different device. Once the world has been exported it could be reassigned to the local storage or stay the world until a new realm is created.

Creating a "realms+/server" solution for worlds being saved onto devices rather than accounts would be very helpful for students that use different devices at home than they would use in the classroom. As well as for situations where if the person is unable to sign in on a device, they can switch to another and have their world/assignment ready for them on that device. I know that they can import and export, but if they are experience issues randomly then they might not think to export their world.
