Wow, I don't think I would feel very comfortable sending a chart up to the front and then back. When you send it up front, do you have to wait for it before you can complete the note in the room?
I think I am missing something.
But, if I do understand somewhat: Let's say you have written a novel in the note and wish to send it to the front, but you do not wish to risk losing it. Why not prior to sending it, hit CTRL - S and send it immediately to your inbox in a nice safe place. Then open it but don't choose to delete it form your inbox and send it anywhere you wish. Once you get the chart back and save it and finish it, then you can delete the backup anytime you wish.
