My previous bank had a feature where you could set one account to draw from another account instead of denying a payment, typically between a checking and savings account, sometimes between a parent and child's account, or a personal account and primary joint account.

I'd love to have a feature like that in Bunq, where you can set one account to automatically draw from a second account instead of denying payment. That way when I keep very little money in my checking account to remind myself to be frugal things will still get paid automatically when they should be.
