first of all great mod <3
I don't know if I can post suggestions here, or if this function already exists (and I don't know how to use it):
First, I love incest games and I know you can rename characters with your mod.
However (I believe) when you rename a character, suddenly everyone in the game is using that person's new name.
But I would like the possibility that only certain people may use the new name.
Fictional example on an unpatched game:
If Pamela is supposed to be the mother and Jason the son, I want Jason and ONLY Jason to call his mother "Mom".
Unfortunately, there are always patches for certain games, then Jason says: "This is Pamela, my mother, blahblah".
And after a few dialogues Jason says: "No Pamela, I don't like to drink water".
Such situations kill the immersion for me.
In this case, of course, I don't want the neighbor or anyone else (unless it's my "siblings") to address Pamela as "Mom".
