At the moment, the scroll wheel does nothing when the now playing screen is displayed.  This seems a waste.

I would like the wheel to engage the scanner so I could reposition in the track just by using the wheel without first holding fwd until the scanner engages.  (Users with long tracks probably would prefer this).

Two other proposals have been made in the forum, which leads to the thought of optional behavior, although I think scanner is the obvious choice.  They are:

volume adjust (it would have to be shown that the wheel is a good volume control)

jump to the active playlist display and navigate in it. (users with complex playlists of independent tracks might prefer this).
