Component request: rotational slider aka "the Knob"

Hi David, hi all,

I'd like to share an idea for a new special parameter component - the rotating knob:

It could be useful for controling angle/circle/cycle related data/geometry.

I imagine it would have the following settings:

start - value at "0:00" (default = 0)
end - value at "12:00" (default = 1 or 2Pi)
min - minimum possible value (default = start)
max - maximum possible value (default = end)
loopcount - boolean (default = false)
infinite - boolean (default = false), if true then min & max obsolete
+ the usual slider settings (rounding, digits...)

example usages:

a) potentiometer
start=0, end=1023, min=0, max=1023, loopcount=false, infinite=false
same as typical slider, but with circular motion

b) crank/winch
start=0, end=2Pi, min=0, max=N*2Pi, loopcount=true, inifinte=false
intuitive control over "winding" count

c) spinning wheel
start=0, end=2Pi, min=null, max=null, loopcount=false, infinite=true
useful for continuous (no stopping on the end-start seam) angle picking

What do you think?

No "Expression" on the Knob, like the slider?

Does the Knob's 'Display" feature ('{0}') make it possible for a knob to show only values from 0..359, no matter how many times it is turned either direction?
