I love PictureFlow and think it's generally well done. What I don't like about it is if you pick a song in PictureFlow and play it, the entire playlist gets wiped out and the Album from which the file you selected is added to the dynamic playlist.
What I'd prefer instead of this behavior is the following:
When selecting a song from PictureFlow, the song is added to the current playlist and played (but not stored in the playlist if it's a file-system playlist) without wiping out the whole playlist.
So, the difference is no wiping out the playlist, but adds the selected song to the playlist dynamically and plays it.
If this behavior is already possible, I can't figure out exactly how it's accomplished, so please describe the workflow if I'm missing something.
