I am impressed by the new color management capabilities in 0.21. Even thumbnails are rendered perfectly

Only one thing could be improved (aside from the slowdown

) ... it would be great to have the profile automatically retrieved from the monitor. This is for us, who profile the monitor regularly, so the new monitor profile doesn't always need to be manually changed in XnViewMP. This would be less error-prone.
BTW the ICC settings could be a bit clarified. I've spent some time figuring it out until I found that the first profile is for monitor and the second is for images which doesn't have a profile embedded (and the latter setting should probably be "sRGB" by default).
