Persisted? I am either totally confused now, or my grasp of the English 
language is failing me (I am still confused).

If I understand things correctly with the Display Text node you can 
change the button labels used for example in the quiz. These used to be 
hard coded in the model, and now can be changed by the user.

That, in my mind, bears no connection to 'Persist' where I would expect 
the END user, the learner to change something and that is 
remembered/persisted for the next time the LO is visited.
