I can understand the desire. It would be a handy functionality, even independently from the demo and when starting with XF the backend can be quite demanding as you are not yet used to how it works, so it can be pretty painful. I remember well back then to have run into the same question and, with the demo running out, being in fear that it would take forever and create many headaches to recreate all the settings I did on the demo after eternal digging through docs, forum and trial and error again from scratch.
