thanks for sharing. At least I do now know why nobody ever posted 
there - it's a permission problem ;-)

All of what you are asking for will be available with the next 
incarnation of the SDK. Keep in mind that everything in the iTunes 
Behaviour is *external* to Remote Buddy and encapsulated in 
Tunes.rbbehaviour. That includes all custom UI elements, the config 
pane, music browser and so on.

I do want to add some more polish to the APIs, though, as I want them 
to stay stable and easily expandable. I hope to release an updated 
SDK soon, though.

Best regards, 
Felix
