Adding a feature idea. Give it a priority (Must Have, Should Have, or Nice to Have) and an effort estimate (Small, Medium, or Large), enough to triage a growing list of ideas without a full project-planning tool.
The feature lifecycle. A feature moves through four stages as it goes from idea to shipped: Idea, Planned, In Development, Done. You can see at a glance where everything on your list currently stands.
Linking a feature to a release. Just like bugs, assign a feature to a planned release to track when it’s due to ship. Marking that release live automatically moves the feature to Done.
