Love the feedback and suggestions! To address your points, here are some of my thoughts:

Indeed. I don’t know if I’d try to use Redux without react-redux. The heavy lifting is mostly already done, once you internalize what connect(props, actions)(App) actually does.

Plus testing pure reducers is a simple affair and separation of concerns makes testing components easier.

I just implemented a component and added simple pagination to it. Not sure how I’m going to add robust unit testing for it. I could get better testing coverage if I’d used Redux in my application instead.
