There used to be an option for Thunderbird to return to message list when a message is deleted. The option closes the message window or tab after clicking on the delete button to delete the message being viewed, thus return the user back to the message list. What happened to this option? I hate the default (and now apparently the *ONLY*) behavior of displaying the "next" message -- which ever that may be. Anyone have any clue of how to re-enable the option to return to message list? Or is that "feature" gone for good?
