Hey; i had this idea that would be pretty good and useful; i don't know how hard it would be to implement; but say you want to have a good look at something with little temperature changes (tens/hundreds of degrees); there should be a scale that you can wrap. For instance, the current one contains all temperatures from 0 to 10000K; but if you could wrap that to 100 and 1000K for an extremely vivid view of what's happening; everything off-scale just being maximum color just as it is now.
This is really a purely practical, no-nonsense feature that can significantly enhance your experience.
