Re-rendering for state changes is a fairly easy thing to do, if you're willing to accept something like useState/setState. It can even be done application-side (without help from the lib). Basically, just wrap all state changes in setState and re-render everytime. Now the optimization I haven't done is deciding whether a child needs to re-render when a parent re-renders. Comparing the props seems like a straightforward way to do this, so I'll probably spend some time over it today and implement it soon.
