I was thinking a new interesting feature, a bit connected to the MoneyBox ( Curve Currency Moneybox ) can be a new way for parents to handle dedicated sub-cards for children or account for children.
Basically setting a threshold on payment and using the card of the parent account that have to accept/confirm payment if they exceed the agreed threshold.
Add a new type of account that is “child of”.
Each “child” account has a lower threshold of max payment day/week/month and a wildcard can be defined for specific category
Payment exceeding threshold need to be confirmed first by parent account (if parent activate this)
Each payment of child is billed on parent selected cards
Each payment of child is notified to parent
Timeline view will be able to filter by child
You can make a custom design for children card as extra fancy stuff
