Recently the list view was added for the forms & checklists scheduler, allowing users to exit a questionnarie and re-entering it again.
However, now, the list is there for all eternity and since this is published to entire groups, there are cases in which it is not desireable for users to see unfinished questionnaires of others. (for instance when declaring receipts).
Also, this list will be there for the entirety of the existence of the scheduler, making it more difficult to manage.
By adding a turn on/off list view button to the scheduler (as is the case for the project planner as well) we leave the decision to the client to (de)activate the list view per scheduler
