One more thing I'd like to see in this tool: tracing in HSL channels. That is, have a "Fill by:" label and H, S, L checkboxes in the controls bar. By default all of them are on and this gives the same result as now. But I can leave only H on and trace a blue area on a red background, even if they are very close in S and L. Or have only S checked and trace a bunch of bright flowers on a dull (low saturation) background. Or have only L and trace the area of similar level of lightness ignoring differences in hue or saturation. I think that would be quite useful in many cases.
How about a more generic "Use Channels" selector, so that you can choose between channels in RGB, CMYK, or HSL, and whether or not you want to use alpha in the calculations?
