I have also disliked knobs in gui applications, but I just realized that
the problem is not with the widget, but how it is controlled.

The knob UI element doesn't have a single operating method. Knobs in
different applications work in different ways. If this would be
standardized, the knob could be a very efficient UI widget. It uses very
little screen space and can be used to display a very broad range of

I propose:
  - To move: press left button on knob, while the button is pressed,
    vertical movement moves the dial (left -, right +)
  - If shift is pressed, the movement will count as 1/10th (or
  - Double click on the knob for entering the value manually
  - Middle click sets the knob to the direction the mouse pointer is
    located looking from the middle of the knob.
 (- Right click would be reserved for context menus)

Anybody know of a good authoritative standardizing body in the open
source front who would be interested in taking this task?
