Milestone: Customize the celebration, and save the accomplishment in habit progress view.

A “milestone streak” feature for long goals (e.g., breaking a 365‑day streak into smaller stages with custom milestone names) would be powerful for motivation.

When you submit, it would help to include:

• How you’d define milestones (e.g., every 7/30/90 days, or a custom list)

• Whether you’d like custom names/badges and celebratory notifications

• Milestones should appear on the habit details/progress charts
