How can I reply to an email in the Mail app directly in the reading pane instead of in a new window?
I want to be able to respond to messages directly in the "parent" Mail app window instead of in a new window that opens for each message reply. It appears this feature isn't available, which (if it's not) is C.R.A.Z.Y. and so irritating. Does anyone know how I can change settings to reply to messages directly in the reading pane?
