Looks good! FWIW I always felt the observable pattern much more intuitive than the redux/reducer style. Something like https://mobx.js.org/ Things get hairy in both, but redux pattern feels so ridiculously ceremonial all to effectively manage a huge global state object with a false sense of "purity". Observables otoh say "fuck it, I'm mutating everything, do what you want with it". |

```
// define observable
this.count = this.observable(0);
// getting
this.count.value;
// setting
this.count.update(value => value + 1);
```
But it also has a redux-like pattern where you can dispatch actions and register reducers with far less ceremony:
```
// define store
const todoStore = createStore({ todos: [], });
// register reducer / producer
todoStore.register('add', (store, payload) => { store.todos.push(payload); });
// subscribe component to store
this.todos = this.subscribe(todoStore, 'todos');
// dispatch
this.dispatch("add", newTodo);
```
It looks like it’s mutating, but both the reducers and update() uses immer* under the hood, so we still respect immutability under the hood.
Cami supports redux devtools so you can use that for time-travel debugging too.
