Ya know what would be awesome? A home screen widget that shows you which card is currently selected and allows you to swipe left/right to select a different card, all without having to open the app. Would make things MUCH easier. Thoughts?
Not sure how closely the US Curve app and the European Curve app are related and how easy it is to integrate functions that are available in one app version into to other app version, but your idea can be voted for here.
