While, already confirmed that the ability to see "Full Family Trees" is in the works, it is not currently available, AND the ability to easily and generally see where your characters fall in history is not available.
I have made a family tree similar to what I'm discussing but it isn't very interactive and does not exist with the World Anvil platform which would be cool to effectively peruse through the world's history of important characters and click on one and be taken to their page.
Basically what it would show is a large canvas with a timeline running vertically down the sides. On the canvas are columns with specific families/bloodlines/dynasties (columns that are easily swapped with other columns in some editing mode for easier organization). Within these columns are characters located vertically in relation to the timeline on the date they are born (don't want to show how long they've lived simply to avoid clutter). For clarity with large families, deceased ancestors could be greyed out and maybe come with a "(Deceased)" tag. Currently living characters would not be greyed out. Above the parent of a dynasty would be a dynasty header and above/alongside new houses could also exist a smaller house header though that is pretty specific. I would also say that something like a "notes" feature could be good to give context to specific characters if desired.
It's a good way to visualize your world through it's characters.
I think the uses for this are as follows:
1. Visual tool that allows seeing the web of bloodlines that exist in a world AND where they fall in the world's history.
2. A way to integrate existing timeline features into the family tree feature that specifically highlights characters and maybe important world events so you can begin to get inside of the landscape that a character would have existed in.
3. Organizational tool to see if there are gaps in world history. This could be a good tool to identify places that could be filled with something OR could be good ways to identify naturally occurring dark ages or ages of peace that help create the narrative of a world.
Only issue I see with having people appear along the y axis when they were born is that if people who are born somewhat far apart get married it might create some wonky situations
The family tree function is what makes a couple of my games possible and you've done a great job. But the above changes would allow it to be more useful and navigable as a tool for viewers.
