Sorry, flooding the board, newbie style…
Something I feel is quite important is a toggle for notification details. If it were possible, I would turn off the payment amount for incoming payment notifications. At the moment, if say, my phone is on my desk at work, when I get paid my phone displays a notification for the incoming payment with the amount shown, which is a bit of a privacy faux pas and has the potential to be problematic if seen by colleagues.
I don’t mind the outgoing payment amounts being shown, but a toggle for each type to hide the amount would be really useful.
