Kris,
I had my eureka moment just a few minutes before I saw your response. In iTunes, I was trying to
right-click and delete using a non-existent context menu. My many years with Windows have taught me well: I can easily turn molehills into mountains.
I finally realized that all I had to do was highlight the folder and hit the Delete key.
I'm migrating from my Nook ST to Marvin on my iPad Mini. I'm totally hooked on Marvin ... it's GREAT!
Thanks,
Marty
