One feature that I personally would find useful would be the ability to Append "Switch to Tuner", to a playlist from the front panel. This would mean that when the playlist finshed, the radio would be automatically engaged.

I find that I typically append playlists at convenient points (like at traffic lights), so that I don't have to play with the player too much while driving. There are situations when I want to finish listening to a playlist and then switch to the radio at the end of the playlist. This doesn't always coincide with a convenient point while driving, as such this would be a useful feature.

A second tuner/playlist request would be for the tuner to continue working while I browse the playlists, until a playlist/track is selected and ready for play. This again would prevent periods of silence/car noise, while driving through towns etc.

Thanks
