Would it be possible to have the parent message always showing regardless of having been read or the action of the toggle messages button.
I want replies to be hidden after being read and the toggle messages button to show/hide replies but not the parent message.
Thanks for your help
You can override view-message-content.php template to manually remove that class from parent message. Currently there is no direct hook to achieve this. Next version i will try to add hook to achieve this easily.
