Hello ,
first, Thank you for the project , it's a great knob with beautiful design.
So after i tried it , i have some feedback i hope it'll help you make this control better ;
First,on mouse move the knob is capturing the mouse position in a line rather than a circle , meaning if I move my mouse upwards in a line the knob will move till the maximum value and vice versa, but If i move it in a circle it'll reach some value and stop at it unless i move mouse upwards (changing the circle diameter)
I hope i made things clear.
Thanks again
