This is the first I've heard of this "copy" operation; I assume you mean
loading a playlist and saving it as another, new playlist.

Okay.

	Foo saves state to a default source, "Red".
	Bar loads state from default source, "Red".
	Foo saves new state to new source, "Yellow".
	Bar saves new state to new source, "Blue".
	Foo saves new state to new source, "Green".

How do you store all four states?  The Red state is
global (+1), Foo and Bar have local states (+2), but
there is no way to save any more states.

If Foo and Bar share a state that's not global, it
costs us twice the space to store the two states
that are identical.

Further, if Foo changes the "shared" state, Bar will
not see the updated state unless it manually copies
the new state from Foo.

Am I missing something?
