This is a request mostly useful for RP servers.
I would like if the name of a player isnt shown directly (since I wouldnt know the names of people I didnt see befor)
So it would be nice if I could look at someone aber after a while I could give him a name by my own, maybe I get something like a friendlist where I can give them names.
So if anyone is lying about his name I wont know it (makes it possible to lie)
After a while, maybe after an ingame month without seeing him you will forget about it and the name will be deleted from your list (the amount of time could be increased if you meet them more often)
Also you could hide your face with something like scarf or a mask (very rogue-like item) to make it harder to be recognised.
Maybe it could interact with an additional skill (trespassing, sneaking ->as told in a different thread)
