You might recall I commented on this a few weeks ago.

Recall Robert was contemplating if we should make the movement linear.
I replied that the current angular way was best for now.

Then I wondered out loud whether we should, as you say, make the
 knob jump to wherever the user clicked.

To which I self-replied: Bad idea!
Accidents can happen, unintended clicked areas etc.
I (as a user) definitely do /not/ want some volume suddenly jumping.
I think the current way is brilliant. Careful and concerted *delta* movement
 means the user really did want it to move.

However I did comment, as Robert observed, that the operation is a bit
 strange, something not quite right perhaps. It is hard to predict at what
 angle one should 'draw out' a radius that makes the knob /not/ move.
Something seems a bit off. You expect the knob to stay put as you draw
 out a certain angle in the same direction as the knob pointer, but it
 counter-intuitively moves the knob, in some different direction.

Cheers. Tim.
