By the way I did have a folder of examples as well. Quite lot of them: https://github.com/react-hook-form/react-hook-form/tree/mast... with codesandbox link too
While it didn't take me that long to do, it does have some weird edge cases that I had to google around for. It would be nice to not have to figure this stuff out with your framework too and would encourage me to try it out more quickly.
I know that formik and redux-forms are popular, but react-final-form and your framework seem to have a lot of overlap. Both seem to be pretty well done.
