Double clicking the title bar of iTunes 11 does not minimize the window With Mac applications I can double click on the title bar of the application and then it will minimize. iTunes 11 lost this behaviour.

Is there a way to restore it?

I'm on OSX 10.6.8 and using iTunes 11.0
This has been an annoying feature of iTunes 11. Other internet forums here and here, are already discussing the issue and as yet are without a solution. Imagine it's something that needs to be implemented by apple.
