That's way I posted screenshot yesterday with main window playlist and track time.
There seems to be a bug in latest version. When I change skin to this version I have a Playlist button in Extended window, but when I click to File Info/Message/Visuals it dissapears.
In Add Visual Tab there is info_head_list.bmp with Playlist, Loop list and Random Play Order buttons.
Maybe you should retain Playlist, Loop list and Random Play Order buttons? Or maybe even better, put Loop list and Random Play Order buttons in main window?
