Typecast Nails Web Font Workflow

Thanks to advances in browser support and growing libraries of quality typefaces, the use of web fonts is seeing exponential adoption. But what has been missing is a workflow that reflects the way designers actually work, providing them with the flexibility to test using thousands of fonts throughout a layout, not just on a small sample of type, and explore the use of such things as OpenType variations and paragraph indentation. And why not be able to automatically generate HTML and CSS from such tests to pass on to devs, as well as easily share your prototype designs and even generate a style guide for clients and partners? Typecast, now in beta, would seem to be able to do all this and more, reminding me how far the use of type on the web has come in just a few years.
