Playlist refresh doesn't exist

[Nightshadow]

Ok, this is strange, i never found a "Refresh Playlist" option in Winamp in the history of my computer life. Please, do something about this! Winamp is the only one player i use for listening to music, and it's the best music player by far, and i can't imagine music in my computer without it. It's kind of frustrating to clear up all the playlist and load the entire folder again, insead of just presing a little circle arrow or something.
I would be so greatful if you will introduce this option in future Winamp editions!
Thank you! Your faithful Winamp user, Nightshadow.
