Awwwards participants have been creaming themselves since this has been released. Good to see how much progress it's made. It's certainly right there next to GSAP as a designer tool.
Mo.js was released as a proof of concept a while back, but has matured into a similarly designed library with a much more precise focus on motion design. While GSAP didn't explicitly ever state it was for such a purpose, a significant number of designers use the library for exactly that in very large clients' animations.
