I noticed that in the “recents” list under Payments, you can add extra accounts to a person. This is a super useful feature, and enables me to send money straight to the correct account if someone has several. The only problem is you can’t edit the person’s name or the account label once it’s added.
I’d love to see more made of this feature - like a contacts list but instead of phone numbers, (meaningfully named) bank accounts under each person.
