Sometimes you don't know if you've added a card to the database. You then search but results return nothing. Instead, there should be an option to add a new card if no results found (instead of returning all the way back to home screen).

Also, after you enter a new card and used a generated password and select 'done'. The card disappears. Sometimes you'll be using that password right away. But then you'll have to seach for it again. Instead, it should stay (or return to) card view until you choose to leave it.
