Wow, looks really interesting!<p>With Flux&#x2F;Redux I have control over when and how data is updated, but that is not the case here. What are the performance characteristics? Is there a limit to the number of observables before performance suffers?<p>There is also the question of routing and history. What is the best way to use observables in a single-page app along with routing and history (i.e working back button)?
