Don't we have that already?
Nope. When you insert a stereo track, Sonar just gives you a single pan pot. All this does is control the balance between the left and right channels, i.e. the relative volume of each. So if you turn it left, you're not panning the whole stereo image left, you're just attenuating the right channel (and removing it entirely if the pot is turned all the way left) - and vice versa. By stereo pan pots, I mean a separate pan pot for the left and right channels. Pro Tools has this:
With stereo pots like this, you can pan the left and right channel individually. And thus you can not only pan the stereo image properly, but you can also control its width and even reverse the image if you like. Of course you can do this with Channel Tools, but we shouldn't have to load a plugin for something so basic - and personally, I've suffered from stability issues with Channel Tools at times (it's still 32-bit).
