Custom categories are a way to group related codex entries - for example, you might have a mafia organisation and you want to group together all the members of the group, their hideouts, the lore/backstory, and any significant weaponry or items they have.
By grouping them together it is much easier to locate your entries, and you can minimize the category if you are writing scenes where they are not needed.
How to make a custom category
To make a custom codex category:
In the codex side panel, click on the cog icon
Select configuration -> custom categories
Select + New
Name your category, choose a colour (optional), choose the associated types (leave all selected if you are unsure), and choose the associated tags. This will indicate the 'tag' that you need to assign to entries to bring them into the category.
Once named, your codex category will appear in the side panel.
Custom categories can be shared across items in a series, but not across unrelated books.
You can edit the custom category by clicking on the pen icon in the codex, next to the category:
How to transfer an entry to a custom category

How to remove an entry from a custom category

How to delete a custom codex category
To delete a custom codex category,
