Add a field within the Form tab for a 'Review Date' and extend Outdated Pages app
Within regulated markets our clients are requesting the ability to trigger notifications / workflows for content which needs to be reviewed rather than unpublish. Currently the only way to achieve this is to use the Outdated Pages app or develop a custom scheduled task. This could be extended with content for review and also trigger a notification email. This would be great to build into the core of the project given the enterprise reach of the product now.
