Keajs has been amazing I upgraded from 0.28 to 2.0 yesterday and had 1 small issue, had to delete [actions.] from the reducers.
I use to use just Redux and it was such a pain.
I know you have added even more features in v2 that I will need to take advantage of.
If you need to add examples https://versoly.com/ is what I built on top of keajs.
Has about 8 logic stores that have 100s of actions, thunks, reducers and some interesting selectors.
