Allow custom codex pages / categories, allow localization therein outside of string-pot file.

[The Plum Gate]

Long title, the codex doesn't seem to permit adding custom folders or entries therein. This makes it difficult for modding to begin with. Help us help you.

Custom folders or entries would allow player created tutorials, in game documentation of mods, and other player created information.

If this is already a thing, someone point me in the right direction.

edit: I remember when I was beta test eve-online, they had an ingame browser that supported HTML 1.0 - it was very basic, but it was super useful and easy to make pages for. Now, I know that was something entirely different, however YAML is not that hard to understand in the context of what's already available to be viewed in the existing codex YAML files.
