I am new to React and Redux so I might not have a well informed opinion. Also, I see the value of Redux and I use it in my projects.

But it's awkward setting up a global event handler with switch statements. And it seems like adding new functionality should require one step instead of three (updating a reducer file, updating an action file, and updating mapStateToProps).

It's like Redux operates on a different paradigm than Javascript and React. I do not think I'm knowledgeable enough to suggest any solutions.
