Controls in a stack

[Peter Haworth]

Thanks Phil.

As mentioned, I haven't really played with backgrounds very much so this
may be a stupid question but why would you want to have a background that
doesn't appear on any card?  I can see that might happen inadvertently when
backgrounds get deleted but is there a practical use for unplaced
backgrounds?
