I know one thing that would make Scrivener an even better writing tool. A character tree! Sort of like a family tree but linked to the character sketches and flexible with relationship statuses like lover, son, father, cousin, best friend, enemy, and the like.
I’m drooling just thinking about how I’d use this because the family tree website I’m using is highly inadequate. There is no BFF relationship so I can connect Summer and Hugo together forever!
