I love that the newest version includes a colour wheel and much kudos for that - however, you can only use it with HSB sliders - no support to use LAB sliders together with the colour wheel.
Why not group the colour wheel together with the spectrum/ramp choices? That's what the colour wheel replaces anyway, and it seems like a much, much more sensible and intuitive fit. It'd also support different sliders (like CMYK, LAB or RGB sliders).
I'll be sticking with Coolorus for now, but the colour wheel is still a step in the right direction!
