I think that the wheel should be configurable by pressing and holding the wheel which brings up a widget with which you select the wheel function (seek, volume, etc) you click the wheel when you have chosen the desired function. This way we can assign any number of future enhancements to the wheel (for example cross fade period could be set in this way, or shuffle setting chosen, or even pitch control of the audio) and the user gets the ultimate choice of what they want their wheel to do.

Well, anyone who has ever set Hijack to do "PopUp0" on the Empeg knob (aka "wheel") knows that I am a big fan of this approach!

The problem with the current Karma setup is that the wheel is way to easy to bump while handling the player, resulting in "seek" induced skips in the music. It is very rare that a user actually wants to use the "seek" function on purpose, so most of the time it is very annoying to have it active by default. But the knob IS the best interface by far for "seek", so..

Cheers
