## Annotation and attribute usage gutter markers

**Feature ID:** `AnnotationUsageLineMarker`  
**Feature Page:** [Annotation and attribute usage gutter markers](https://espend.de/phpstorm/plugin/php-annotations#annotation-usage-line-marker)  

Annotation classes and PHP attribute classes receive a gutter marker when the project contains indexed usages.

The marker opens a lazy usage target list, making it practical to jump from the annotation implementation to code that applies it.

### Code Examples

```php
# Provider class:
/**
 * @Annotation
 */
final class Audit {}
```

```php
# Usage target:
/**
 * @Audit(event="product.created")
 */
final class Product {}
```
