It would be very handy if you could set certain buget for individual accounts so that they are automatically replenished at the beginning of the month from another account (for example salary account).
For example, I have a budget of 350€ for food and drink per month. If at the end of the month there are 35€ left in the account, only 315€ will be automatically transferred from the salary account to the food and drink account at the beginning of the month. So there is no complicated account management and I can simply specify in the budget account that it will be filled from account X every month up to the amount Y.
