Hi Monzo ,
I love the feature Monzo has that tacks your spending abroad, and provides a report when you return home. What I would be great is an option to see a running total of your spending in a foreign currency while you are away. This would make it much easier to keep on top of your spending during a holiday! Maybe even with an option to set a budget amout a duration when you make your first purchase abroad, with warnings when you approach this amount.
