System Sounds, etc.
Isn't it annoying when you are listening to your music and a little pop-up or something makes a noise, that just does not fit in with your music? I think a little tick box in the preferences, to: Mute all else (i.e. everything except WinAMP). Possible? Maybe.
Anothere nice feature would be (for the playlist), if you could right click a song and 'send to XX' and type in a number, and it moves that song to a position that you specify (it's difficult moving things round when you have multiple thousand playlist entries).
