Hi Guy and Mike,
I don't think you were ignored. I suspect it's just that nobody has a good idea. That's why I didn't post. I hope someone from Brennan will see this and put it on the list to be investigated.
The last time I had something go haywire in a playlist, it was a direct result of me trying to have the B2 do more than one thing at the same time. It took me tw and a half hours to get things straightened out again. Moral of the story: don't ask the B2 to do more than one thing at a time. Seriously. I've seen ample evidence of that. And others have confirmed as well.
