Ok that was not it.
Ok its kinda like this...your out harvesting and you come across a Critter Den you would simply put your mouse on it and would show you a list of rares that would come from the critter den.
Same thing for Plain Roots you would put your mouse across it and would give you a list of rares know for roots (exp: glowing Flower etc) Does that make since? I seen it somewhere and its driving me crazy hehe I think you have to make some changes with a.txt file or something I don't know if it was here or not.
I use the Fenix UI mod with add-ons from other UI's and still have not found it anywhere...I hope this helps would love to know as its driving me really crazy here!
It would also do the same for qestion marks I belive, not sure on that one.
