Show Completed Items On Front End

We are considering this plugin on an intranet site. Users are subscribers for the most part and don’t really access the admin dashboard at all. Everything is front-end.

When I embed the list in a page or post using the shortcode [todochecklist], items are removed as they are completed. If I set the attribute to completed=1, then it ONLY shows completed items.

Is there a way to keep completed items in the list along with uncomplete items?
