I'd like to add tracks to the "On-The-Go" playlist while a track is actually playing. Most of the time, I play my iPod by using Shuffle Songs. When I hear a song that I'd like to hear again, I'd like to press and hold the middle button to have it add to the On-The-Go playlist. We should not need to scroll through tons of songs, reading them one by one, to add them to On-The-Go.
If you have a way to get this into the next version, that would be great.
