My thought process going forward is that i want to add more traits that have strong perks with minor detriments and vice versa. This will let you specialize you empire even more and let you get around the trait pick limit a little. Let me know if you like this approach here.

Also if you are interested in being a developer for Just Traits feel free to let me know. I always enjoy having partners on projects like this and I could guide your through how to make a mod for Stellaris if you havent before/ don't have much coding experience.
