It doesn't seem to work, or I'm not sure how to get it right, but I'm sure you put .icc profile under new folder in Inkscape directory under share/color/icc, and Inkscape should be able to detect them, but from my end, it does not seem to work. Also, would it be possible to hide tabs in the color sections, and force Inkscape to stick with CMS? Is there some limitations to CMS that I'm not aware of? Does filters offset color informations? This is one feature I have never saw the use until recently.

Thanks,
