I'm sure that this has been mentioned before but;

I'd really like it if I could jump in the car, and by making a single selection to change 'user', the following would happen:

Current Users running playlist, EQ, info mode, timecode.. gets stored;
New Users previously running playlist, EQ, info mode, timecode... gets recalled.

..and whenever a search or playlist selection is performed, a wendy filter tied to the current User is used.

So, I could have eg the following 'Users'
Me.
My wife.
Family.
The Friday Night Posse.

etc, all with their own unifed settings. It'd also be really cool if we could tie in favourite visuals to this

(Oh, since this is a wishlist and can we have some way to distinctly select a given user from hijack? I have visions of using an iButton to select this - wave my keyfob at my dash and everything changes...)
