I went to see the version in-game, to ensure that I am using the most recent (wowup thinks I am) but then I see the only addon listed in blizz's Interface > AddOns list is Kui Spell List. However, in the AddOn list (from BetterAddonList) shows I have 5 Kui modules enabled, including Nameplates and Nameplates:Core.
