I watched a tutorial on yWriter5 a few minutes ago and I noticed there isn't actually a section for character database. (Unless I missed something? Please correct me if I'm wrong!)

You DO make a character database when you add a character to a chapter just for that character. For this particular project I'm working on, I don't like that because my main characters won't all be introduced in the first chapter and I'm a little OCD so I want my database in the same software as the rest of my work.

What I did to remedy this is I made a Chapter 0 and named it "Character Database" so I can put the characters I have now into it, and I also have a spot to add all other characters I add later in one nice little spot.

I hope this helps!
