I do not recommend this mod. It's not just a UI mod (affects saved games, so you can't just turn it off and on). Apparently it hasn't been maintained in 2 years. Gathering Storm already now has a production queue.

This mod seems to break Barbarian Clans mode (game doesn't crash, but you can't properly interact with the barbarian camps). When you click a barbarian camp, the description for each interaction option just has "$treat option info$", and you can't select any of the interaction methods.
