Can we get more consistent back button behaviour? It would be nice to have back button take you back in the same way as the back button in the top left corner. Sometimes it does, other times it just exits the app.
Can you add the reverse exchange rate. Often I’m used to seeing the exchange rate expressed in one way, it would be useful to show both Cur1/Cur2 as well as the reverse Cur2/Cur1 when exchanging.
