I just posted what I think is a workaround to the problem of continuing to write content after your players have played the first session

Not fully tested that yet but hope it works and helps you.
Having a Export/Import Characters option for the GM would be really useful however. I can see times when for the sake of avoiding bloat; or (and I'd really like to be able to do this) drop one player out for a session, because maybe they cant make it, and bring in a guest player/character.
