@Chazrox cool.
Another suggestion for the skirt it would be useful to be able to do a circular gradient , if that is the right term ? SO not up dwn , but from center.
Also snapshot would be more useful for me at least with transparent background.
Or if that is tough maybe to be able to set the background for the knob in the theme.
Or just a simple background color setting so you are making the knob on the same background color as your UI. EDIT: Found the BG color, perfect !
OR ...hehe, being able to import a screenshot into the background so you design the knob in situ as such.
.. When setting colors I mostly use hex but always have to flip though the other color options , maybe it could remember last used color selection method ?
Also, unless I am missing it, the arcs need a pan setting/ center .
