🤔 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.

Seems like this is different from just using steps since you can still set the value between steps. I think this is a pretty advanced use case that may be better suited to have implemented by using a controlled value.
