The QuadCurve EQ is pretty much my favorite EQ of all time but I don't use it as often as I would like largely because of the inability to float the window, have multiple open at the same time, resize it, add it as a normal effect rather than ProChannel, etc., etc.. They could release a separate QuadCurve product that adds stuff like this plus soloing, etc. and I'd happily pay a $100 (or whatever) upgrade fee.
