They are tired of this discussion? ;p

To me, the main problem is the lack of agreement on wether 
plain knobs should be radial, linear-vertical, linear horizontaly, 
linear-both.

That was part of my motivation for fan-sliders:

I still think classic knob graphics imply radial and anything else 
is visual lying. Quite a while ago I worked on a concept of widgets 
with a knob-size footprint and graphics that hint at their non radial 
nature.

First I worked out 2 ways how they could be linear without using 
only one axis. The first image contains 2 charts to explain 
the 2 ways:
- using distance the pointer has been move from the center after 
mouse-down
- projecting the current position to the nearest axis

There was one developer who pretty much insistet on knobs in  
Phat and who was at one point willing to implement my design(s), 
but then dropped it just because I called them not-knobs at 
some point (plus being busy otherwise, I guess). Nobody else was 
in sight, so I stopped there.

Looked at Ardour 2 recently? I think you should have a look at 
the new sliders and panners.
