I like to skin my Winamp player just as much as I like to skin my computer.
Classic Pro is a very popular plug-in for Winamp and gives you the ability to use easy to skin ClassicPro Skins.
With ClassicPro, you get the most out of Winamp since it is full of essential features and is even more extendable by Widgets.
The objective for this Modern Skin platform was to enable "Winamp Classic" skinners to make their own Modern skins just as easy as they made Classic skins.
The ClassicPro layout is based on the bundles Winamp skin, Big Bento.
ClassicPro make use of a single-user-interface (SUI) to show all the Winamp components (Video, Playlist...) unlike some SUI skins, ClassicPro can be used with the Playlist in the main area witch should be useful for the Winamp users that do not make use of the Media Library. ClassicPro skins can also be resized smaller until it hides all of the Winamp components.
