I would like to have a “list view” for viewing and editing collections. Perhaps it would be a repeating element bound to a CollectionDatasource with a layout embedded in the definition which applies to the data source items.
The Patternfly web site describes the concept well: “A List View displays data in rows. Each row displays the same set of attributes, although not necessarily displayed in columns, and the attributes may wrap. The List View omits column headers and other visual noise, making it a cleaner visualization than a data table.”
