Profile editing on Nosta works now. Some refinements are still to come, like addressing both "name" and "display name", better validation, and tips for potentially confusing fields. Another important feature is indicating when there multiple profile versions were found on relays, letting you pick which one you want to use moving forward, and then updating all relays accordingly. There's always more to do, but the basics should be there now. If you try it, please share your feedback.
