I was able to figure that much out thanks! My main issue is just deeply wanting to delete all the default templates in the options setting. It's slightly irritating to have 7 templates in my drop down list that I'll never use before I get to my first custom one that I want when I could've been allowed to remove them.
Also, tangential question: Have you ever considered adding annotated map viewing to Nebulous? Like the type where you can navigate an imported image and place pins linking to other objects. I'm thinking of the ones found in competing worldbuilding programs like LegendKeeper, chronographer, world anvil, and world maker.
I specifically love the unique way nebulous visually organizes information and automatically links content, and I feel like having a similar behavior to spatially organize articles would be really strong here.
