I might be in the minority but I regularly use the joystick and like it. One thing that would be a definite help to me would be the ability to 'sticky left click'.
It's a little difficult to click and drag sometimes, particularly when I have to alt+tab from one window to another. Yes, I could change their size and location but it would be easier to just map something like 'Num+Left Mouse' so that doing so would act as if I'm holding down the left key until I click it (or the mouse button) again.
