As the amount of content in a Collection grows, it becomes very hard to select a set of similar items to review, edit, delete, etc. If I could filter the Collection by a date range, or by a field that would make this process much more efficient. For example: in the attached screen, I have a Collection named "Resources" with a field named "Resource Type". If I could use a filter only Resources that have a Resource Type of "White Paper", it would be much easier to know how many items of that type are in the site, and to find the one I need to work with.
