| Ok, let's forget it. It's just odd to me to have an allFoo() method which
| returns a list of Foo, but the currentFoo() method returns a Foo which is
| not in allFoo().

| displaying a list of albums for the user to select, then this is ok for me.

| selections.
Well that could be resolved by having a flag with which the plugin can tell 
the widget about this request.
