Currently, after a service user is deactivated, their completed forms are still displayed on the form view from the Dashboard.
I think by default the completed forms view should only display forms for currently active service users, as otherwise there will eventually be a long list of forms for people who are no longer service users. This could also be a concern in terms of data retention.
Having a service user filter which defaults to 'all active' but can be set to any defined group or the 'deactivated' group would allow flexibility in this view.
