I'd like to see students be able to co-construct a space at the same time.
Another feature that would be helpful is to allow students to create their own space, but then link it to another space that someone else created. For example, student A could create the first scene in a story and student B could create the second scene. They are able to link them together so that when a viewer enters student A's scene, they can move to the next space, which is the one that student B created.
If there was a feature to allow one student to create a space and invite other editors to the space, that would accomplish both wishes. This is a feature that is enabled in the newest version of Tinkercad. It allows students to work collaboratively and is extremely useful.
