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.Neel commented
I have 2 friends with same name like Priya and priya (lowercase p). So, when I add an expense and search for my friend's name. I am confused as which one it is. So, if I can edit a friend's name just locally for my reference as "Priya from San Francisco" and "Priya from Boston" it would be very useful.
Budgets definitely make a lot of sense. They’re not a feature on our roadmap yet (we’re a tiny team, and still focused on other improvements), but hopefully they’re something we can work on in the future.
