### 🤔 Expected Behavior?

- Allow to add multiple ticks (marks) to the slider
- May have optional labels above/below the track
- Clicking on the label should move the slider to the corresponding value
- Snap to ticks based on cursor movement (the behavior may vary depending on movement speed)
- Keyboard actions (e.g. arrow keys) should remain unaffected

### 😯 Current Behavior

Currently, React Spectrum and React Aria do not have such features.
