Campaign Setting

[sablevarg]

I am starting a heavily modified game world/campaign. I saw where there was a tab called Campaign Setting. (Midgard/Southlands - Trade Tongue is common & elves are known as 'elfmarked').

I couldn't figure out how they set that up. But a better question is: would that help manage my character creation? Would it help show just the things I want to allow or is it just useful for renaming things in bulk?

If anybody knows, please help me on this. Both on exactly what it does & help in setting one up.
