Active state missing

Active state when clicking is missing. :)

Just to be clear what's missing. When the minimize, maximize or fullscreen button is clicked, the background gets a little darker?

Also the fullscreen button should point inwards when the window is already in fullscreen mode.

exactly, the background should get a little darker on click.
