Improve components performance

**Feature request**
It would be great to have notifications for store.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_notifications` with default `false`.

Start by locating the store implementation and the existing configuration handling for options such as `enable_notifications`. Read how related events or status messages are emitted, then clarify what notification behavior and production deployment requirements should count as done before changing the configuration.
