All good ideas

1. True, I've forgotten about folders.
2. Yes. I've added a feature request in kenai to remember this.
3. Not hard at all, just need to find a place in the UI to put that

4. I like that one too. Added feature request.
5. Not a single operation, but you can add album songs to the iTunesDJ playlist (right-clicking on each song), and then download that playlist. However I do need to add a button or something there to be able to clean the playlist to begin with.
6. Not sure about this one, because when done from javascript this can eat up a lot of CPU, so the experience can vary depending on the machine.
Thanks for the feedback, I'm glad you signed up to the forum.
