Unread Content: Mark as Read

Currently, you have to open an item before it will be marked as read.  In the Expanded activity view where the response text is visible, you can often read the entire response.  Having a one-click option to mark a response as “read” (thinking checkbox) would be a real time saver since many people will use this as a type of “inbox”.  

Thinking through the page logic, you would probably want to immediately update the item status as "read" in the database, but not actually refresh page content.  In case a mistake was make, user could uncheck the box in order to reset it as "unread" in the database.
