Thank you for sharing these comments with us.
This functionality is something that we have discussed within our team and we all agree that we would love to implement in the future.
In the meantime, a good workaround is to save a copy of the lessons you are interested in. You can do this by selecting a lesson, clicking on the three-dotted icon at the top right of the lesson plan and clicking 'Save as ...'.
You can later find, edit or play these lessons by going into 'Your Library'.
I hope this helps and keep the feedback coming!
