Hi your mod helped me when developing mine (Show me the Money), and I made some local changes that I wanted to share in case you find them useful.

I wanted to see everyone, not just rulers. So I made the type = to character and for neighbors I changed it to:
every_living_character = {
limit = {
in_diplomatic_range = root
}
add_to_list = ranking_candidates_list
}

And for the whole world I removed the ruler limit. I was astounded how much money some of the religious heads had. Like 10000 gold for one of them. Thanks

Awsome mod! its like reading Forbes most richest in the world 😆
