There is a patch for replacing the HSV color picker sliders with LCH 
sliders. But the patch has some side-effects on the other panels, and 
will be nicer to use once the color picker is color-managed. Also, an 
outline on the color square showing the boundaries of in-gamut vs 
out-of-gamut colors would be nice (the sliders already show when a color 
is in or out of gamut):
