 Nice decision - I also like it.

 May be we should add the following logic too:
 If ctrl or alt or meta is pressed, the slider is moved in oposite direction
(with the same treatment of step size as function of the mouse button index)?

 I personally always keep my hand over alt or control when in X and when
mouse is in hand, since alt-drag1 moves the window, alt-drag2 resizes it. So 
it would be nice to use 'ctrl' and 'alt' as a modifier to mean 
"move in opposite direction" (since one of my hands is over those modifiers).
Same for spinbutton (alt or cntrl+ click on arrow changes the value in the
opposite direction).
 What do you think about this?

 It's nice that you've listen to any of my proposals :) Others are still
waiting for you.
