I’m sure I’m not the only person who keeps their money in a pot, has like £200 in their checking account, and withdraws money from the pot whenever their checking account is running low. I have to open the day every day or two to do this, but it would be super easy to automate.
You can just give people the option to say “when my checking account balance falls below £X, withdraw £Y from this pot”. The best place in the UI for this would probably be scheduling pot withdrawals.
