I would love if MobX's computed-value expressions would become more natively integrated into React (or better yet into JavaScript itself). As a quickfix, it would be great if it were possible to use MobX with decorator syntax in create-react-app without ejecting, because MobX without decorator syntax gets a bit unwieldy.
Edit: Reason might be the way forward. https://reasonml.github.io/
However we have found over the years that following that simple model leads to more complicated application code and some problems are hard to solve. So we're trying to address them. React itself is getting a little more complicated, but our hope is that it makes your apps overall simpler and with fewer quirks to learn to make a full-featured app.
