I have wondered if it would be good for debugging (assuming you're using Redux or something with a time traveling debugger) to put UI events in the store, too.

I have wondered if it would be good for debugging (assuming you're using Redux or something with a time traveling debugger) to put UI events in the store, too. Then you can have a complete picture of "how did we get to this broken state"if you need it. I would keep that stuff separate from data with a prefix, so that you could easily distinguish between the two.
