Hi,
for most of your components you can change the appearance in a wide range, e.g. SmoothButtons with colorfrom + colorto + mirrorcolorfrom + mirrorcolorto and that also active/inactive/hoovered, and so on.
But at JogWheel there is nearly nothing, but the from- and to-color would be very necessary when you want to have a very long/high jogwheel that replaces a scrollbar.
So I request a colorfrom + colorto + colormirror for the JogWheel.
