Change Case Ownership Plus Release Notes 2.22 - 2.24
Now CCOP can be configured for use with case feeds as a publisher.
CCOP can be configured to enable user filtering by selecting the text field to filter on during initial setup. For example, a user can filter on first name to narrow down the list of possible users to select from. This option is only available if your configuration is setup to display a certain number of users rather than a search text box.
Salesforce does not allow emailing to a queue when using an email template, as a workaround, the current user will be emailed instead.
