On the Conversations tab, the open notifications will show in yellow. The screen also has checkboxes in which checked indicates the notification is completed and unchecked indicates it's open. 

Users can complete the notification from the Conversation tab. However, the system will still automatically complete the notification when a new conversation message (notification) is sent. Additionally, there is a new Global Setting to stop the system from auto-completing the notifications. 

The Send to User dropdown list will show the last 7 users that the logged-in user has sent a notification to at the top.
