I'm not a designer so I don't know how good it is and I only skimmed the article but the high level concepts in the article around managing design workflows make sense, e.g.
> Figma solved this problem. Designs in Figma are not just stored in the cloud; they are edited in the cloud, too. This means that Figma users are always working on the same design. With Dropbox, this isn’t true. The files may be stored in the cloud, but the editing happens locally—imagine the difference between sharing Word files in Dropbox vs. editing in Google Docs.
It sounds like Figma reduces friction in the collaboration process by clever use of cloud based and browser coordination. It's not innovative but it's a good application of existing technology to the design space.
