The filter cards
Filters appear twice: as Apply Filters, the last step of the wizard, and later behind Manage Filters on the view page. Both show the same cards, grouped by module.
For a case view: CASE (Submission Date per form, Case Status, Grouped Submissions), SITE (Sites, Site Types, Site Status), REGION (Regions), FORM INFORMATION (Forms) and USER (Users, User Roles). Other view types have their own - a Task view filters on Task Type, Priority, Status and Due Date; a User Activity view on Activity Type and Activity Date; a Contact view on Contact Type, Organization, Position and Status.
Every control is a searchable list with checkboxes. Tick the values to keep - Approved and Flagged under Case Status, say - and rows that match any ticked value stay. Leave a control empty and it does not filter at all.
