Firstly, I love you.
Secondly, there’s one thing about your app which makes me feel like I have an OCD. I have various card from different banks and countries because I do work in a few different areas.
When I add a new card, it comes first in the list but it may not be my primary payment method. The same for bank accounts, I add them for withdrawals but they may not be my primary account.
If you could give us the ability to set the order our cards and accounts show in, that would be great.
