I added a custom field, checkbox type named "Complete" because i'd like an easy way to mark cards as 'completed' but i don't want to have due dates.
Now, I'd like to filter cards according to this field; specifically cards that do not have this checkbox checked. How can I create a filter to only display cards where this checkbox isn't checked? I've seen suggestions that 'Dashcards' can do this, but this powerup doesn't seem to actually enable any filtering features. It seems to only allow me to create an additional card that displays a count of cards that match those conditions.
