One issue is the placement of the knob relative to the edges of the screen and what you do when the pointer (ignoring touch) reaches them.
That is why being able to adjust with both horizontal and vertical movement is a plus. Take a look at zita-mu1 for an example. It is also important to continue watching the position of the mouse when it leaves the application window.
