The possibility to save, replay and maybe share Kingdoms would certainly be nice to have. For the sharing part, the following is a solution that requires nothing more than text data.
When you enter the kingdom selection, you can select your cards via Mouse, or you can type in the card name. If you copy and paste a comma separated list of card names (including landscapes), you can fill in the card slots in one go.
