Two of the four ideas picked from the Maybe/Sure feature audit: - Idle cash: a 5th proactive alert flags a depository account (checking/ savings/cash) sitting at or above a configurable balance with no transaction touching it for a configurable number of days. - Category hierarchy: categories can now have one level of subcategories (Groceries -> Alcohol). Dashboard/report aggregations roll a subcategory's spending into its parent's slice. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
