So, I don't remember what exactly what it was called, I know that it was ouf based, the screenshot was of a druid in tree form (I don't use druids Idk what its called) and his name was treelet and for some reason, lyncolors stick out with it. I've found a UI that brings back memories, it looks almost like it but I can't find the one in looking for.
Here is the UI that looks almost like it..
