My name is Bill (aero1) really like Foobar2000, I've made a modest donation.
I have a feature suggestion/request. I also use Winamp but primarily because of this one feature.
I can select directly: 'Play - Folder'. And a window is opened from which to select a folder. The window has a memory and suggests the last folder I had selected. Many of the things I listen to have many parts in a folder, such as a symphony.
I suggest you provide this as a direct selection from the top menu.
