I can see how this would be a huge help for people who have many friends with the same name who refuse to add their last name to their accounts! This isn’t on our roadmap yet, but it’s something we’ll consider in the future.Guangyang Li supported this idea ·Guangyang Li commented
I am using splitwise more and more and I realize I am kind of deep user of it. However, with more and more friends on it, it becomes really hard to tell their usernames. About half of my friends won't use real name on website (or even on the whole Internet), so I think it's IMPORTANT to add name editing. On the other hand, I don't think it's hard for splitwise, adding a nickname for friends is nothing but adding a nickname table in your DB.
