// Note about the application structure:
// - The user interface and its state is managed by React/Redux.
// - Persistent storage to SQLite and Web API is handled outside of React/Redux using regular JavaScript (no middleware, no thunk, etc.).
// - Communication from React to SQLite is done by calling model methods (note.save, etc.)
// - Communication from SQLite to Redux is done via dispatcher.

// So there's basically still a one way flux: React => SQLite => Redux => React

// one we know it should be fixed (or added here).
