This is similar to how you can save your work in a video editing suite as a "Project", then re-open it and continue from where you left off.
This would be really handy if the disc setup is particularly complicated, as in, I've just spent better than an hour tagging all my tracks and setting all my flags and order weights, then the damn computer crashes!
Maybe even an option to auto-save every five or ten minutes once the initial "Project" has been created?
It would also be great for re-ripping a file from a backup without having to re-enter everything.
