Thanks for the added info, Helen.
I've got a pretty detailed setup for my Kindle Collections (via the Kindle Collections plugin), so I'll probably use s/r to copy some of the metadata I currently use to a custom column or two just for the Sony Collections, in addition to my existing genre and series columns. (Yes, I'm a wee bit of a control freak when in comes to collections.
)
It should be interesting (and fun!) to get used to a different way of doing things. It will be here tomorrow, and I want to use it stock for a bit before rooting it.
