Refactor lib for better readability

**Description**
Currently components lacks proper notifications support.

**Proposed solution**
Add configurable notifications with sensible defaults.

**Priority**: Low/Medium

Start by locating the components under lib and checking how current configuration and user-facing events are handled. Clarify which notification events and configuration options are intended, then define sensible defaults and verify that configurable notifications work across the affected components.
