If I compose a message in MP by typing it directly in the window (and not creating a file in plain text or MS-Word or whatever to import), is there a way to save it? It would be useful to be able to return later to a draft to reconsider or finish/refine it before posting. One doesn't always want to publicly post right away or post partial fragments of a much longer message, even though the preview window helps. At the moment, I assume that if I enter text, when I close the window or switch to another computer, the text is "lost" regardless of whether I have yet clicked to preview or not. Is this something that can be implemented here, similar to the way email systems let one save drafts when they haven't been sent yet.
