Is your feature request related to a problem? Please describe.
I'm currently using the re-frame-like xframe for global subscriptions and state updates. However, in many of my use-cases I merely need get-like and get-in-like subscriptions and assoc/update(-in)-like handlers.

Describe the solution you'd like
Reagent's ratom + cursor compatible with reacts hooks. Like this but global.

Describe alternatives you've considered
xframe has been my alternative so far. I think it would be nice to provide a less opinionated solution to global state updates and subscriptions.
