Show contacts that have a balance with a different color.
Why not show the little person icon next to the friends name with a color? Red if you owe them, Green if they owe you? Sometimes you want so see who owe you money individually and I have to go through each contact to see if they owe me or not.
We actually tested this at one point and thought that it ended up looking too distracting, but it might be worth reconsidering. I’ll pass on a note about this. In the meantime, you can always get a list of everyone who you have a balance with from the Dashboard screen. Apologies for any inconvenience!
