I can watch video in whatever player, where i can listen music. I can watch video in Winamp, so why is a command for winamp? And its logical that I dont use command /w when I watching video. I use VLC for play music & video files. So when I am listening music I want to tell anyone what I am listening now. So this is reasons why you have add support for VLC to ApexDC++, which is cutting edge.
But if you doesnt like this idea, so write as well that you dont want this feature and I will be quiet :)
