I'm not sure if this is really the place to be suggesting things or not.
But I feel having a timeline where you could use dropdowns to add chars and events would be nice.
Especially if it was split up into births, deaths, events and notes.
I currently use a spreadsheet for these things but it would be so nice to have it built into notebook.
Here's a screenshot of what i'm currently doing to show what I mean

Is that something anyone else would be interested in at all?
