I don't see how that is materially different to it looking at the scratch partition and extracting the current running order ?

It isn't. But it would allow you to create the playlist and then SAVE it on the player at the point you want it saved. Then you would be free to mess around with the player some more instead of not wanting to re-shuffle for fear of losing your work.

I dunno, though. I personally would never have a need to use such a feature. If I'm going to build a complex playlist, I want to be sitting at my desk, not driving. I was just thinking out loud.
