I would like there to be an option to set a minimum balance for the main account (i.e. £1000). Then the day before payday, any money in excess of the threshold (i.e. balance is £1251.60) would be automatically transferred to a savings pot. So in this case £251.60 would be scheduled to be moved to a separate pot. It would need to consider any pending transactions but it would be really good to start each month at roughly the same balance if you are on a consistent salary, and would simultaneously help build up the rainy day fund.
As a Customer,
When it is the day before my monthly salary is paid into the account
and I have set a minimum threshold set
and I have money in excess of that threshold
then Monzo automatically transfers the excess amount into a separate pot
