Show "Balances" initially collapsed
The default display when choosing the "Balances" window it's to show who owes whom. For our coffee club it is more convenient to list each member's balance only (and not also say who that member owes our it's owed an amount). If the members balances are listed we can easily determine who should pay for coffee next...the one with the highest debt.

Hmm…it looks like our iPhone app does this already (it collapses all but the first person’s balances), but our Android app doesn’t. I’ll pass on your feedback and see if that’s a change we can make in a future update.

Add additional filter in the friends tab that shows friends who owe me OR whom I owe money.
