Nicknames for contacts

I know that this suggestion has already been made like this one for example to name a few, but I would like to add on to this by adding why I want this to be added. I'd like the ability to nickname or rename a contact (not to be confused with Server Nicknames or A.K.A.) like from the standard name "ExampleName3" to "Friend John" for example -

Nickname Suggestion Reasons:

• To easily distinguish if the contact is a friend or not.
• To maybe read the name better.
• To avoid people from renaming themselves without telling you and as a result, forgetting who they are (nicknames are permanent until the "nicknamer" resets name to default).
• To know who someone really is (someone's real name).

Rant:
I hope these reasons are valid and people can relate to them. And yes, even if the reasons aren't relatable, they're going to really help me know my friends on discord better. I don't know which Topic is better, whether it is Other or Difficulty Seeing, Reading & Accessibility. I picked the Accessibility one. Not only that, but I really hate it when people just change their names on discord completely without me knowing and having to check all the message history to know who they are. Thank you to everyone who read and understood this and don't forget to tell me if this is a valid suggestion.
