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.
