A few suggestions I have thought of:
I’d love to have the ability to hide a pot, so it doesn’t appear in the pot list. I know you can lock a pot, but I am thinking that with one toggle button you could show/hide the hidden pots. This would be partly if my friends or family catch a glimpse of my monzo app, I don’t want them seeing the balance of my ISA when day to day I’m not that flush, and partly because of the old addage “out of sight, out of mind” which for longer term goal pots, you aren’t tempted to start pilphering them.
The ability to be able to assign recognised retailers to take from certain pots. I love that direct debits can now be paid from pots and this is very useful, but I keep having an issue where tesco/sainsburys get declined because I have forgotten to move money out of my groceries pot. If Monzo could recognise a handful of grocery/fuel retailers and automatically pay from grocery/fuel pots it would reduce user input and save time and reduce declined transactions.
