The previous update was fun and all, but it got some reasonable critique as it was really hard to work with big hierarchy trees. I decided to spend a week more to make hierarchy trees actually usable and enjoyable.

Hierarchy tree is still available for cultures and religions. But due to the last change listed above it is very easy to add tree view for other elements when needed.
