This package is not meant to be the powerhouse that Redux is, nor a replacement for Redux on all projects. There are very real and deliberate limitations. By trading some functionality and best practices, it rids of learning curve and boilerplate. If you have a large project that requires strong features, you should use Redux for it. If you have a smaller project or a team of junior developers, ReactN will serve you better.
If you can conceptualize your desired behavior as optional or without boilerplate, I would love the implementation details as feedback.
