Satchel remains a great and relevant resource. I’ve found many aesthetic and practical uses due to how easy it is to understand & edit, fitting it to my specific needs.
Some may prefer it, but I personally wouldn’t use Satchel if it were built in React. It has a steep learning curve, I’ve heard many performance complaints and I don’t see a point outside of projects with tons of developers, who would most likely develop their own system anyways.
Regardless, thank you for the resource it has helped in my development quite a bit.
