Here's my wish list:

1) When I use Smart Exchange, I can download a lesson and open it as a Notebook File. Then I can edit it. However, within Lumio itself, I don't see how I can download my own files. Likewise, if a colleague shared a link to a lumio file, I can edit within Lumio, but I don't know how I can download that lesson and work on in Notebook. Maybe we can, and I just don't know how?

More importantly,
2) Lumio has a lot of great templates, and ready made resources. However, I don't see those same resources on Notebook. Since I like to first create lessons in Notebook, having these features available in Notebook would really be enhancing.
