Yes, I saw that it is based on the new proxy api. That is why IE is not supported (but who cares anyway :)).
When I looked at your code the state management looked so much cleaner than in my SteemDesk code. Redux really works great, but I have the feeling that the boilerplate is slowing me down. Have you tried something like Rematch?
Thanks for remiding me of rematch, I guess I have somehwere a bookmark but couldn't find it anymore. For me the rematch api looks way better then traditional redux or even the
react-easy-state. I guess for my next project I will userematch. :)
