Congrats on the release, etc.  Just a couple of minor bugs/complaints:

1. I know you're going for an online banking app feel, but entering the password each time is a bit of a pain. It seems to happen too often for me.  Perhaps make it optional (i.e. user logs out) or let the user play with the auto log out settings?  Even better, spend limits for PIN only operations?

2. I set the currency to GBP but there are still instances of amounts being displayed in USD (e.g. when requesting funds).

3. Would be nice to default to wallet view, rather than directory.
