Astonishing application. It seems to know where visual output is being done through an application and simply grabs it.
All the same, I'd far prefer having this capability for MilkDrop from within it, no need to install another application (and that application doesn't grap output with winamp paused), and bluntly, it seems like a very obvious feature (though I certainly wouldn't know how to add it myself).
Still - thanks
And I'm happily grabbing cool stills from this cool visualization plugin.
