I think many of the sorts of people who frequent r/webdev are familiar with Josh W Comeau and his CSS for JavaScript Developers course, which exists for me as more-or-less the gold standard of online courses for web developers.
Does anything remotely similar exist for Figma? I feel like a couple of the Piccalilli courses are almost there, but I think I have the mechanics more in mind here, where both of those courses feel more about the soft skills of communicating around-about design than about actually using Figma.
