My initial concern was that the traits that I was considering spending culture on listed as their benefit a leader trait, but there is no popup that tells me what that leader trait is.  I suggest adding a popup be added everywhere a leader trait is mentioned that explains what the leader trait is.  The text of the ideology traits in my original post are examples of where this would add value.

My secondary concern was that I do not know where to look to see what ALL of the possible leader traits are so that I could identify the ones that I want to watch for and go after.  I am thinking of something like the Technology Library screen that lists all of the technologies along with information about what they do.
