I'm sure this one is straight forward and most likely someone watching this course already knows about it, but we had a little quality of life improvement on Blender 4.5, where the blackbody control for the light temperature can be done with a quick toggle straight on the light settings panel.
Essentially doing the same thing under the hood, but we don't have to go into the node editor anymore for it. Yay!

Yay! Starting on the next chapter now. Looking forward to this topic since the beginning!
