While categories offer an extremely high level of grouping for goals (e.g. work, health, family), tags would be a much more granular way to class individual steps.
A potential use case of this would be like "contexts" in the GTD methodology. Tags could be set up for "Office", "Home", "Errands", etc, for tasks that can only be completed in a certain place or as part of a certain routine. It will then be easy to filter down to a tag and see all matching steps across all goals.
