What I think Paolo is aiming for, is an auto top up-feature from a (general) bunq donor account where his income arrives to other (budget) bunq accounts. A feature that has been requested for many times before on this forum, but not implemented in bunq yet. It is possible from accounts on other banks, but not within bunq. Or: why not make it possible to set a schedule for a top up when you select another bunq account?
Correct me if I'm wrong here, but what Paolo (and many, many others) wants is to set a minimum balance on an account. If the minimum amount is reached, a set amount is transferred from the main account to the specified account so that the specified account always has the minimum set balance. This would be a feature which would help bunqers to manage their budgets even more specific and gives a better flow of money amongst the different budgets.
To put it in code:
If BalanceOnAccount < SetMinimumBalance Then FetchMoneyFrom(SetAmount, SetDonorAccount)
...maybe this way the coders at bunq will understand what many bunqers want...
