kpat can play numbered deals using an 8 digit hash to restore the initial state of a game. The number of each deal appears in the title bar of the game but I've not found a convenient way to copy this and it isn't always convenient to have a pen/paper for recording this. A simple way to store the game number (copy?) would be nice. While I'm here a layout for the buttons that separated |undo redo| from the others buttons (a spacer) would be handy. It's a little bit too easy to press the wrong thing in some situations
Use Ctrl-D and there you have the current game number as editable/copyable text.
