This would require mounting the disk drives as read-write in the car. Contrary to main design principle.
That's why I said emplode should do the work, not the player.
Although a complex scheme of saving it to the scratch partition and creating on the next synch might work, I don't expect the Empeg guys to implement it any time soon.
The current running order must be saved to the scratch partition already, after all it survives reboots.
How about Emlode lets you look at the contents of a saved bookmark and optionally copy that into a playlist
I don't see how that is materially different to it looking at the scratch partition and extracting the current running order ?
