Since I used fan sliders in my app, I've been thinking a lot about them, and I'm
not sure they're such a great idea, for the reasons outlined above. And I saw
some sound engineers getting really confused when first trying them. But this
might be because they were just surprised.

Well, as I previously said, I think that knobs can make sense in certain
situations. So I'd rather see the phat knob improved ;) I think that's a really
cool widget, it provides a very clear visual indication, but it only supports
the circle movements.

It would be great if there were runtime options to customize the phat knob
behavior, to also support up/down and/or left/right, fine-tuning with a key
modifier, etc..

Providing alternative styles would also be very cool.
